Overview

Towering

At 22,841 feet, Aconcagua is the highest peak in both the Western and Southern Hemispheres and one of the Seven Summits.

Remote

The approach follows the quiet Vacas Valley to Aconcagua's seldom-visited eastern face, traversing the mountain on descent via the western side.

Supported

RMI's partnership with Grajales Expeditions provides fresh food, dining tents, medical staff, and full Base Camp infrastructure so climbers can focus entirely on the climb.

The entire trip was great, from Mendoza to the summit and back. In thinking back on the trip, there were some great team members and we were lucky with the weather and the mountain, but what really put the icing on the cake was the guide team. They just simply made things fun, period.

Kirk L.

Aconcagua pierces the sky above the rest of the Andes at 22,841 feet, the highest point in both the Western and Southern Hemispheres and one of the Seven Summits. It is a mountain that earns every foot of its elevation: the altitude is relentless, the weather is unpredictable, and the approach is a three-day trek through the winding Vacas Valley that gradually introduces climbers to the scale of what lies ahead. By the time Base Camp comes into view, the mountain has already made an impression.

RMI climbs the Guanacos Variation on Aconcagua's eastern side, a quieter and more aesthetic route that sees far fewer climbers than the standard approach. Three successive camps are established above Base Camp, navigating the mountain's sprawling rock moraines and towering snow penitentes on the way to high camp at 19,600 feet. The itinerary is built with acclimatization days and contingency time at each stage, because on a mountain of this altitude, patience and preparation determine outcomes more than anything else.

What separates this expedition from a standard high-altitude trek is the level of support RMI and Grajales Expeditions bring to the mountain. Fresh food and dining tents are maintained at Base Camp, medical staff are stationed on the mountain, and every logistical detail from airport transfers in Mendoza to equipment carried from the US is handled before climbers ever set foot on the glacier. The summit of Aconcagua is a serious objective. The experience of getting there should not feel like one.

WHY RMI

Setting the Standard Since 1969

RMI has been leading climbers on Aconcagua for decades, and the guides on this program bring that accumulated high-altitude experience to every aspect of how the expedition is run. RMI guides hold wilderness medicine certifications, carry comprehensive medical and rescue kits, and maintain radio and satellite communication throughout the climb. Daily weather forecasts via satellite inform every movement decision on the mountain, and the itinerary is built with acclimatization days and contingency time at each stage to give the team the best possible chance at the summit. RMI uses its own climbing equipment brought from the US, ensuring the standards of quality and reliability that define every RMI expedition are met on Aconcagua.

“I've recommended RMI to several friends on several different occasions. Although I haven't climbed with any other guide companies, I truly believe RMI is one of the top notch guiding services in the world.” — Del B.

What makes this expedition run as smoothly as it does on the ground is RMI's long-standing partnership with Grajales Expeditions, the premier local operator in Argentina. Grajales provides fresh food and dining tents at Base Camp, medical facilities and doctors stationed on the mountain, and the logistical infrastructure that supports a seamless experience from Mendoza to the summit. That partnership means every detail is handled before climbers arrive and throughout the climb, from airport transfers and hotel arrangements to camp operations deep on the mountain. RMI brings the guiding expertise; Grajales brings the on-the-ground knowledge and operational precision that makes the difference on a mountain of this scale and complexity. To learn more about RMI's international partnerships, visit our Partners page.

Risk management and climber security are built into every layer of how this expedition operates. Small team sizes mean guides can closely attend to each climber, monitor acclimatization, and make sound decisions as conditions evolve. That level of attention is not incidental to the experience on Aconcagua. It is what separates a well-run expedition from a difficult one.

Qualifications

Fitness

You should arrive in excellent physical condition and prepared for steep climbing with a heavy pack, strenuous physical output over consecutive days, and a summit day that can exceed twelve hours on the mountain.

Experience

Climbers should have previous experience at altitudes above 14,000 feet and be comfortable with crampon technique and ice axe arrest before arriving in Mendoza.

Altitude

This program reaches 22,841 feet, making it one of the highest non-technical mountaineering objectives on earth, and climbers should be prepared to perform physically and mentally at extreme altitude over multiple consecutive days.

Aconcagua is one of the most demanding high-altitude mountaineering objectives in the world, and the mountain's sheer elevation is the defining challenge. Climbers are expected to arrive with a working command of basic mountaineering techniques and the fitness to apply them over eighteen days on the mountain while carrying loads of 50 to 60 pounds. The altitude, the duration, and the remote environment combine to make this a serious undertaking that rewards thorough preparation and personal accountability.

“This program was much harder than expected and harder than almost any mountain I've climbed. I'd not hesitate to recommend participants complete a winter skills clinic or a Rainier summit before attempting this mountain…” — Mike W.

Training should emphasize sustained aerobic output, uphill travel with a heavy pack, and the ability to perform at high effort over multiple consecutive days. A recent and active climbing history matters on Aconcagua. Climbers who have been consistently active in the mountains within the last three to five years, have experience above 15,000 feet, and have completed multi-day expeditions carrying full loads are the best positioned for success. The closer you get to your program date, the more your training should reflect the specific demands of the climb: long days, heavy packs, and sustained effort at progressively higher elevations.

Climbers completing the Aconcagua expedition gain experience with high-altitude mountaineering, multi-day expedition pacing, and acclimatization management on one of the world's great peaks.

Recommended Climbing Resumé

Your climbing resumé should include:

Previous experience at altitudes above 14,000 feet*

Comfortable with crampon technique and ice axe arrest*

Multi-day mountaineering or backcountry experience carrying a full load and moving between camps*

Climbing activities within the last three to five years

Strong aerobic fitness with a focused training program in place

Items marked with an Asterix (*) are considered mandatory prerequisites for this program.

Physical Fitness Training

Mountaineering places sustained demands on your body and your ability to stay composed under effort. Even very fit people find that moving uphill with weight, for long hours, in variable weather is a different kind of challenge than most everyday training.

Preparation matters. Fitness directly affects how well you move, how much you learn, how the team functions, and how enjoyable the experience is overall.

Start early. Begin training well in advance of your program with the goal of arriving rested, resilient, and confident in your capacity for sustained effort.

Train intentionally. Emphasize aerobic endurance, uphill movement, and strength that supports long days on your feet. Core stability, balance, and mobility all play an important role in efficiency and injury prevention.

Train specifically. The closer you get to your program date, the more your training should resemble the demands of mountaineering: hiking uphill with weight, moving steadily for hours, and recovering well enough to do it again the next day.

Across RMI programs, strong preparation typically means being comfortable with long days of continuous movement, carrying a pack appropriate to the objective, and maintaining focus and decision-making when tired. Technical skills are taught or reviewed as appropriate to each program, but fitness is something you bring with you.

Nothing contributes more to a successful and rewarding experience than arriving well prepared. Plan to be in excellent physical condition and ready for a demanding day in the mountains.

Fitness And Training Resources

Our guides have decades of experience training for alpine objectives, and we've done our best to put together relevant resources to help you with your expedition preparation.

Acclimatization

Acclimatization is the process by which your body adjusts to lower oxygen levels at altitude. How well this happens has a direct impact on how you feel, how you perform, and how much margin you have as the climb progresses.

Program length and structure matter. Longer expeditions are designed with ascent profiles that allow your body more time to adapt. Shorter programs often move through altitude faster than the body can fully adjust. In these cases, climbers typically experience mild but normal symptoms associated with early acclimatization rather than full adaptation. This is expected and accounted for in program design.

Physical conditioning plays a major role. Well-conditioned climbers generally have more energy available to support the acclimatization process over consecutive days. Fitness does not prevent altitude exposure, but it improves resilience, recovery, and the ability to function well while your body is adapting.

How you take care of yourself matters just as much as the itinerary. Arriving healthy and rested, staying well hydrated, eating consistently, and managing heat loss all support acclimatization and performance. These factors become increasingly important as altitude, duration, and cumulative fatigue increase.

RMI programs are structured to balance objective goals with appropriate acclimatization strategies for the terrain and timeframe involved. Individual responses to altitude vary, but strong preparation and good self-care remain the most reliable ways to support a positive experience at elevation.

Your Role as a Climber

Mountaineering is both an individual challenge and a team endeavor. Before any program begins, RMI works directly with prospective climbers to confirm that everyone joining a team is genuinely prepared for the demands ahead. Depending on the program, this may involve conversations with our office staff, a review of your climbing history, or feedback from guides and other climbers who know your abilities. The goal is straightforward: to ensure that every person on the rope belongs there. We ask that each climber hold themselves to the same standard:

  • Meet Program Prerequisites: Arrive with the climbing experience, qualifications, and gear outlined for your program.
  • Arrive Prepared: Come in top physical and mental condition. Strong preparation directly affects your performance, your teammates' experience, and the team's overall safety.
  • Be Informed: Review all pre-departure materials and communicate any questions to the RMI office before your start date.
  • Medical Clearance: Provide any required medical documentation and inform the RMI office of any changes to your health before departure.
  • Team Consideration: Act considerately toward all team members and respect the customs and values of the areas you travel through.
  • Environmental Respect: Follow Leave No Trace practices throughout the program.
  • Communicate Honestly: Accurately represent your fitness, health, skills, and equipment to your guide staff, and keep them informed of any changes during the program.
  • Stay Accountable: Attend all briefings and gear checks, follow guide instructions, and take personal responsibility for your equipment, hygiene, and readiness for changing conditions.
  • Self-Assess Continuously: Evaluate your fitness and readiness honestly against the demands of the program. Your willingness to do so contributes directly to the safety of the entire team.

The standards we set exist to protect everyone on the team. RMI holds all climbers accountable to them, and we take seriously our responsibility to build teams of people who are ready to be in the mountains together. RMI reserves the right to remove a participant from a program or send them to a lower altitude if our guide staff determines, in their sole discretion, that the participant is not physically, technically, or psychologically prepared or capable of participating, or for any other reason that may compromise the safety, health, or well-being of the participant or the group. In such cases, no refunds or credits will be issued, and the participant will be financially responsible for any additional costs associated with an early departure, including evacuation, transportation, lodging, and meals.

Equipment

What You'll Need

The Aconcagua expedition operates at extreme altitude over twenty-three days, and the gear list reflects decades of RMI guiding experience on high-altitude mountaineering objectives in the Andes and around the world. Every item has been selected to support steep climbing, heavy load carries, and extended expedition living at elevations up to 22,841 feet, where conditions can change rapidly and the margin for being underprepared is slim. Every experienced mountaineer refines their kit over time, but this list represents what RMI expects climbers to bring to the mountain.

Not every item may be used during the climb, but all required equipment must be carried and available. RMI uses its own climbing equipment brought from the US, ensuring the standards of quality and reliability that define every RMI expedition are maintained throughout the climb on Aconcagua.

Guide pick™

Each RMI program includes a required personal equipment list built around the specific terrain, conditions, and objectives of the climb. Every item serves a purpose and supports safety, efficiency, and comfort in the mountains.

fuel for the mountain

On Aconcagua you will need 19 mountain lunches. All of your mountain lunch items should weigh 12 - 13 lb.

Breakfast and dinner meals on the mountain are included as indicated in our Trip Itinerary. With the exception of hotel breakfasts, most restaurant meals are on your own. You are responsible for your own bottled water and drinks.

“Everything was organized perfectly. Katrina's cooking was outstanding! I only lost three pounds on the trip (always went back for seconds whenever she offered them.)” — Craig F

ABOUT YOUR MOUNTAIN MEALS

Mountain Lunches

Mountain lunches are eaten during short breaks throughout the day. We continually snack to keep our energy levels up while we climb - lunch begins just after breakfast and ends just before dinner! Avoid packing any items that require preparation or hot water.

The importance of having foods that are genuinely enjoyed cannot be overstated. Eating properly is the key to maintaining strength while in the mountains. In order to combat the loss of appetite at altitude we aim to have a variety of foods that stimulate the whole palate, from sweet to sour to salty.

Recommended mountain lunch items: dry salami, smoked salmon, jerky (turkey, beef, fish), small cans of tuna fish, individually wrapped cheeses such as Laughing Cow or Baby Bell, crackers, bagels, candy bars, hard candies (Jolly Ranchers, toffees, Life Savers), gummy bears, sour candies (Sweet Tarts), cookies, dried fruit, nuts, energy bars, GORP mixes, and drink mixes (Gatorade/Kool-Aid). All items should be commercially packaged.

Argentina does not allow the following items through Customs: cheeses, fresh meats, dried meats, fresh fruits, and fresh vegetables. Other food items may pass inspection but that decision is at the discretion of the customs inspector. Items which are generally okay include jerky and dried fruits as long as they are in their original packaging.

We will have the opportunity to purchase additional food in Argentina but we recommend you take what you need and only supplement with local food if necessary.

Breakfast

The breakfast menu includes items such as instant oatmeal, cold cereals (granola), breakfast / granola bars, hot drinks (coffee, tea, cocoa, cider) and local fresh fruit.

Dinner

Dinner usually begins with soup and ends with dessert, followed by a round of hot drinks. Healthy one-pot meals, incorporating fresh local food whenever practical, are served as the main course. One typical main course dinner might be spaghetti with sausage and fresh vegetables. Another meal might be chicken fajitas with cheese, tortillas, onions, and peppers. There are limitations, but the menu is planned to offer good variety and ample portions.

Travel, culture, & logistics

This page covers the practical details you’ll want to review before your trip, including travel logistics, entry requirements, local considerations, and required policies. Taking time to understand these details ahead of departure helps ensure a smoother experience once you’re on the ground and focused on the climb.

TRAVEL INFORMATION

Travel Advisories / Warnings

Please confirm any current travel advisories/warnings as well as entry requirements with the U.S. Department of State.

Getting There

Travel to Mendoza, Argentina (MDZ) typically takes 18 - 27 hours from the U.S. depending on your departure city, available connections, and flight times. Flights generally arrive in the afternoon on Day 2 of the itinerary.

Departing flights may be booked for any time on Day 22 of the program.

Entry Information

A valid passport is required when traveling to Argentina. Your passport must be valid for 6 months beyond the expected return date. U.S. passport holders may stay up to 90 days without a visa.

We suggest making a copy of the first two pages of your passport and keeping them in a separate bag as a backup. A copy should also be left with your emergency contact.

Airport Arrival

Upon arrival at the Mendoza airport, proceed to the Immigrations desk for foreign travelers. They will provide you with an entrance permit adequate for your stay. Please check the date to ensure it covers your complete stay in Argentina.

Once you receive your bags from Baggage Claim, you will proceed to Customs. There will be a random selection of bags for inspection. Be sure to keep all your bags together.

Upon arrival in Mendoza, take a taxi from the airport to our hotel.

In-Country Transportation

The provided transportation as stated in the itinerary is via private vehicle.

Immunizations & Travel Medicine

For the most current information on inoculation requirements and recommendations, please refer to the Centers for Diseases Control and Prevention.

Traveler's Health

Travelers may suffer from upset stomachs when in foreign countries. There are some basic rules, however, that can help keep you healthy.

Hygiene - It is important that you wash your hands thoroughly before meals and after using the restroom. If water is not available for washing, we recommend using a hand sanitizer.

Water - The number one rule is: don't drink the water, and that includes shower water and ice! Brush your teeth with purified water rather than tap water. You should check bottled water for a good seal and use a napkin to wipe excess moisture in drinking glasses. Take care with fruit juice, particularly if it has been diluted with water. Carefully clean the tops of bottled beverages before opening.

Food - If it is cooked, boiled, or can be peeled, you can usually eat it. Salads and fruits should be washed with purified water or peeled where possible. Be wary of ice cream and shellfish. Always avoid any undercooked meat.

Medical Emergencies

Aconcagua is a remote mountain without easy access to definitive medical care. We are our own rescue team. A rescue team headed by the Mendoza Police operates on the Ruta Normal, which joins our route above 20,500'.

The medical facilities in Buenos Aires and other urban areas in Argentina are very professional. We will work with our tour operator to access an appropriate level of care should the need arise.

ADDITIONAL TRAVEL INFORMATION

Argentina Country Facts

Argentina is a country of high Andean peaks and salt flats, massive ice fields, a vast thorny wilderness known as the Impenetrable, a spectacular Lake District, penguins, flamingos, caimans, and capybaras.

The country's economy is focused around food processing, motor vehicles, textiles, chemicals and petrochemicals, printing, metallurgy, steel and agribusiness. This is a new Argentina, one emerging from a severe economic crisis with a renewed sense of identity and purpose.

Buenos Aires, the capital of Argentina, has become one of the most talked-about travel destinations in South America. It's not just a cliche that their steaks are highly acclaimed and their wines are delicious and affordable. And if you have the opportunity to experience a soccer match during your time there, you will find them full of passion and intensity.

Mendoza is at the center of the Argentinian wine industry. Though surrounded by hot, dry desert, Mendoza’s extensive irrigation system both beautifies the city with greenery and allows for grape production. Summers, January in particular, can be very hot and dry in the city, with temperatures often above 100°F.

Weather

The practical climbing season on Aconcagua is January and February. We will certainly share the mountain with other climbers during these months, but the better weather and higher likelihood of reaching the summit are well worth it.

Many organizations advertise "less crowded" expeditions in November and March. Be aware that November is early spring and sees substantial snowfall and poor weather, and extreme winds and colder temperatures may be common. March is known for notoriously high winds (the Vienta Blanco or "white wind") and most tour operators have ceased operations at that time.

While there can be no guarantees of perfect weather in the mountains, our expeditions take full advantage of both the weather and route conditions for this expedition, and utilize prime months for optimal climbing experiences.

Cultural Etiquette

The people of Argentina are generally very warm and friendly to tourists. Although it is not expected that we dress formally, we should dress modestly. Casual and comfortable clothing is suggested along with comfortable shoes. Showing expensive cameras, watches, jewelry, etc. is considered unseemly and may attract unwanted attention.

A handshake and nod show respect when greeting someone. When entering a shop or home, politely use a greeting such as buenos días (good day), buenas tardes (good afternoon), buenas noches (good night). Similarly, upon leaving, even if you've had only minimal contact, say chau (goodbye) or hasta luego (see you later).

Argentines are typically proud of their country and culture. They are well-educated and tend to be cosmopolitan and progressive. Because a majority of Argentina’s population originated from Europe, Russia, and the Middle East, travelers typically have little trouble fitting in.

One interesting area of etiquette is the very Argentine custom of drinking mate, a South American infused drink, which comes with its own set of rules. Foreigners will be given lots of leeway here and breaches are likely to cause amusement rather than offence.

Porter Assistance

Porters are available to help carry gear above Base Camp. They can be arranged at your request through your guide. Porters carry loads of 20 kg and prices depend on where on the mountain they are needed, varying from $335 to $665 dollars for a one-way trip. If you plan to use a porter for the entire expedition you can expect to pay approximately $2,150. Payment is due in cash at the time of service. Porter fees are not included in the trip or permit fees and are in addition to the amount we suggest you bring as spending money.

Electricity

Electricity in Argentina is different than in the United States. Argentina has standardized type I sockets and plugs. Type C plugs and power points are still commonly found in older buildings. Both are used for 220-240 volt, 50 hertz appliances. U.S. appliances will require plug adaptors, convertors or transformers. Please visit http://www.worldstandards.eu/electricity for more detailed information.

Money

The current currency of Argentina is the Peso. Check a financial newspaper or www.xe.com for the current exchange rate prior to departure.

You should anticipate spending between $500 - $700 while in Argentina. This amount is adequate for personal spending money including restaurant meals, drinks, pocket money, and the Support Staff Tip Pool.

Cash machines are readily available in Mendoza, but become increasingly difficult to find outside of the main urban areas.

Credit cards are accepted in most, but not all, areas.

Everyone has a preferred way to carry money. Some use money belts, others have hidden pockets. Whatever you do, be aware of pickpockets and thieves in any area which caters to tourists.

Tipping

Everyone approaches tipping a little differently. Whether or not a person tips, and how much, is completely dependent upon the individual; here are some suggested tipping guidelines for your trip.

Local waiters, drivers, and other service personnel expect to be tipped. Ten to fifteen percent is standard. Some restaurants and hotels add a 10% service fee to bills in which case, no further tip is required.

Support Staff Tip Pool: We recommend that each climber contribute $100 to the Tip Pool. This is collected at the beginning of the trip and will cover group tips for all our support and mountain staff throughout the program.

Our guides work hard to ensure your well-being and success on the mountain. If you have a positive experience, gratuities are an excellent way to show your appreciation. Amounts are at your discretion and should be based on your level of enjoyment. Tips for excellent service normally average 10 – 15% of the cost of the program. If you would rather not bring the guide gratuity with you on the trip, you can send a check or call the RMI office to pay with a credit card upon your return.

Risk Management Policy

Please clearly understand that mountaineering is inherently hazardous. Managing risk is RMI’s number one priority. Our guides manage significant hazards inherent in mountaineering, but they cannot eliminate them. Objective hazards include rockfall, icefall, avalanches, slides or falls by individuals and rope teams on steeper slopes, weather-related problems including cold, heat, high winds, and other unnamed dangers that can occur while climbing.

You are choosing to engage in an activity in which guided and non-guided climbers have been injured or killed. While those accidents are indeed infrequent, they may occur at any time and be out of our control. We ask that participants acknowledge the risks and hazards of mountaineering and make their own choices about whether or not to engage in this activity.

PARTICIPANT RESPONSIBILITIES

Mountaineering is both an individual challenge and a team endeavor. Each Participant is required to share in the responsibility of the safety and success of the team. For this reason, we ask that each Participant:

  • Possess the climbing prerequisites required for this program.
  • Possess the necessary physical and mental fitness required for this program.
  • Be responsible for knowing all pre-departure information.
  • Provide a signed Physician’s Certificate stating that the Participant is medically qualified to join this program.
  • Update the RMI Office if there are any changes to your health or medical information before departure.
  • Be properly attired and equipped as outlined in the Equipment List.

  • Communicate with your guide staff on the mountain if there are any changes in your medications or health.
  • Adhere to the advice of your guide staff.
  • Continue to self-assess throughout the program, measuring your fitness, health, skills, and abilities against the demands required of the program.

RMI reserves the right to dismiss the Participant from a program or to send the Participant to a lower altitude at any time if the RMI Guide Staff determines, in its sole discretion, that the Participant is not physically, technically, or psychologically prepared for or capable of participating in the program or for any other reason that may compromise the safety, health or well-being of the Participant or the entire group. If this decision is made, the Participant will not receive any refunds or credits and will be financially responsible for any additional costs associated with an early departure, including but not limited to, evacuation, transportation, hotels, meals, etc.

Zero Tolerance Harassment Policy

Rainier Mountaineering, Inc. (RMI) does not tolerate harassment or mistreatment of our participants or employees. Inappropriate conduct under this policy may include conduct that creates a disrespectful, intimidating, hostile, degrading, humiliating, or offensive environment for a participant or employee. Engaging in such conduct is a violation of this policy.

RMI may consider conduct to violate the policy even if it falls short of unlawful harassment under applicable law. When determining whether conduct violates this policy, we will consider whether a reasonable person could conclude that the conduct created an intimidating, hostile, degrading, or demeaning environment.

Violation of this policy may result in removal from a program, as well as refusal to provide services indefinitely. We place the utmost value on the safety of our participants and employees. Please report any incidents to RMI management.

Age Requirements

All participants must be 18 years old at the time of registration.

Photo Release

RMI’s Photo Release outlines the terms and conditions for using your likeness in photographs, videos, or other digital media.

I hereby grant Rainier Mountaineering, Inc. (RMI) or its affiliates permission to use my likeness in a photograph, video, or other digital media (“photo”) in any and all of its publications, including web-based publications. By granting permission, you allow RMI to utilize these media for lawful purposes.

  1. Authorization: You authorize RMI to edit, alter, copy, exhibit, publish, or distribute the photos.
  2. Ownership: All photos become the property of RMI and will not be returned.

Summit Attempt Policy

RMI cannot guarantee that you will reach the summit. Weather, route conditions, your own abilities, or the abilities of other climbers may create circumstances that make an ascent unsafe, and you or your entire group may have to turnaround without reaching the summit.

Failure to reach the summit due to a person’s own lack of fitness or to any of the events associated with mountaineering (such as weather, route conditions, avalanche hazard, team dynamics, etc.), are not Rainier Mountaineering, Inc.’s responsibility and will not result in a refund, credit, or reschedule.

GENERAL POLICIES

RMI’s program schedule and itineraries are subject to change or adjustment based on a number of factors. These include, but are not limited to, route conditions, weather, group strength, terrain, or other environmental factors, and many other factors. RMI has complete discretion to change plans to accommodate any of these or other factors, including but not limited to, increases in program fees, changes to program schedule or itinerary, and changes to guides or staff, as necessary for the proper and safe conduct of the program. Once the program has started, the Lead Guide will decide on any changes to the itinerary, including ending the program early if the continuation of the program may compromise the safety, health, or well-being of the group.

We reserve the right to cancel any program due to inadequate signups, weather, route conditions, or for any other reason. In such a case, we will make every effort to reschedule the Participant on a different program date. If rescheduling is not possible, we will issue the Participant a refund for all program fees paid to RMI, less any non-refundable payments made on behalf of the Participant to secure any of the included land costs provided for this program, including but not limited to, hotel accommodations, transportation, transfers, tours, group equipment and food, permits, and local outfitter services, prior to the cancellation of the program. Additionally, RMI cannot be responsible for any non-refundable expenses the Participant incurred in preparation for the program (i.e., airline tickets, hotel reservations, rental cars, equipment purchases or rentals, etc.).

Once a program begins, there are no refunds or credits for weather-related cancellations or for a program that may end early due to weather, route conditions, or any other circumstances that may compromise the health, safety, or well-being of the group. Furthermore, if the Participant decides for any reason not to begin a program or discontinue a program at any time, no refunds or credits will be issued. The Participant will be responsible for all additional costs associated with an early departure, including but not limited to evacuation, transportation, hotel reservations, meals, etc.

Land Costs are provided as a package, and refunds or credits will not be issued for any unused meals, accommodations, group transportation, or other unused costs. Accommodations are based on double occupancy. A Single Supplement Fee will be charged to those Participants occupying single accommodations either by choice or circumstance. If you are willing to share a room, we will make every effort to pair you with another same-gender team member. We will match willing same-gender team members based on the order of registration date. If we are unable to match you with another same- gender team member, a single supplement fee will be charged. The availability of single accommodations is limited in most of the hotels where we stay, and single accommodations are not available while in the mountains.

The Participant understands and agrees that RMI assumes no responsibility or liability in connection with any travel and hospitality services provided to the Participant by other companies in connection with the program, including but not limited to, the services provided by airlines, hotels, rental cars, and transportation companies. In addition, RMI is not responsible for any act, error, omission, or any injury, loss, accident, delay, irregularity, or danger by a supplier of travel or hospitality services to the Participant in connection with the RMI program. The Participant will be responsible for all costs associated with any travel delays, missed connections, or missing baggage that requires additional arrangements (separate transportation, hotel accommodations, meals, etc.) to be made on your behalf for you or your baggage to rejoin the program.

Frequently Asked Questions

Aconcagua draws climbers from around the world, and the questions that matter most are the ones that determine whether you are genuinely prepared for a mountain of this altitude and commitment. The answers below address how this expedition operates, what the climb actually demands, and what to expect from the approach, the acclimatization schedule, and summit day on the highest peak in the Western Hemisphere.

Health and Travel

Do I need any vaccinations before traveling to Argentina?

No specific vaccinations are required for entry into Argentina from the United States. However, we recommend consulting your doctor or a travel medicine clinic well in advance of your departure to discuss any recommended precautions for your specific health situation.

Is altitude sickness a risk on Aconcagua?

Yes, and it is one of the most significant factors affecting summit success on this mountain. Aconcagua's extreme altitude means that even well-conditioned climbers can be affected. RMI's acclimatization schedule is designed to reduce this risk, but climbers should familiarize themselves with the symptoms of altitude sickness and discuss prevention strategies, including medication options, with their doctor before the expedition.

How much is the Climbing Permit?

Every foreigner climbing Aconcagua must obtain a Climbing Permit from the National Park. The price is dependent on the time of year and not finalized by the Park until the beginning of the climbing season. During the high season (December 15 – January 31), the permit costs approximately $1,500 USD. Note that the permit date is based on the date of entry into the Park (Day 4 on our itinerary).

Do I need a visa to visit Argentina?

US citizens do not currently require a visa to enter Argentina for tourism. We recommend confirming current entry requirements with the Argentine consulate before departure, as requirements can change.

Is travel insurance required for this expedition?

Yes. RMI strongly recommends comprehensive travel insurance that includes emergency medical evacuation coverage. Given the remote nature of the climb and the international travel involved, evacuation coverage in particular is essential.

The Approach

How long is the trek to Base Camp?

The trek to Plaza Argentina, our Base Camp on Aconcagua, is a three-day walk up the Vacas and Relinchos valleys. The trek ascends from 8,800' to 13,800' and is approximately 23 miles long.

Are porters available to help carry my gear?

Yes. Porters are available to help carry gear above Base Camp. They can be arranged at your request through your guide. Porters carry loads of 20 kg and prices depend on where on the mountain they are needed, varying from $335 to $665 dollars for a one-way trip. Payment is due in cash at the time of service. Porter fees are not included in the trip or permit fees and are in addition to the amount we suggest you bring as spending money.

When is the climbing season for Aconcagua?

Aconcagua is climbed during the Southern Hemisphere summer. The season runs from November through March, and RMI runs and recommends January and February, when weather and conditions are most stable.

On the Mountain

How much weight am I carrying in my pack?

Mules help us on the approach to Base Camp, so backpacks should be approximately 20 to 25 lbs. Once we begin making carries or moving camps above Base Camp, pack weights increase significantly. It would not be uncommon for a pack to weigh 50 to 60 pounds depending on the climber's size. Summit day packs are around 20 pounds, carrying only clothing, food, water, and other essentials for the summit attempt.

What is the pace like?

We use an easy to moderate pace throughout the entire trip. The adventure as a whole, and certainly the days when we are carrying heavy loads, is generally characterized as strenuous. While the distances we cover on a daily basis are relatively short, the altitudes to which we travel are very high and the days of hiking and climbing can be very challenging. Overall, our guides set a reasonable pace at the appropriate speed to cover the distance we need that day without going too quickly or too slowly. This is true of summit day as well.

Why does RMI use a high camp at 19,600'?

RMI's 19,600-foot high camp is at an altitude that has allowed our team members the greatest chance of making the summit. Climbers who use higher camps often have difficulty adjusting to that altitude. RMI's camp is situated at an elevation at which most climbers can sleep comfortably after acclimatizing lower on the mountain.

Do I really need crampons on Aconcagua?

Yes. Depending on the season's snow and ice conditions, crampons may or may not be needed to ascend certain parts of the route. It is far preferable to bring your crampons just in case than to be forced to turn back on the summit bid because of unanticipated icy conditions.

What tents do we use?

We provide three-person, four-season tents for every two climbers.

What are the toilets like?

Basic pit-toilets are available near Base Camp. En route, where no toilets exist, we use bio-bags to collect our solid waste so that it may be transported off of the mountain. We recommend that you bring hand sanitizer for use after visiting the toilets.

What is the food like on the mountain?

Please see our Food details for an example of meals while on the mountain.

What is a typical summit day like on Aconcagua?

Summit day begins with an early alpine start from High Camp at 19,600 feet. The route traverses the mountain's northwest flank, passes the abandoned Refugio Independencia, and climbs the Canaleta, a 1,000-foot couloir leading to the summit ridge. A straightforward traverse from the top of the Canaleta leads to the summit at 22,841 feet. The full day typically runs twelve to fourteen hours or more and is the most physically demanding day of the expedition.

What are my chances of reaching the summit?

Aconcagua is known for low industry-wide summit success rates. The primary factors are altitude, weather, and individual fitness and acclimatization. RMI's itinerary is specifically designed with acclimatization days and contingency time at each stage to give climbers the best possible chance at a summit attempt when conditions allow.

What happens if weather prevents a summit attempt?

Three weather days are built into the itinerary specifically to accommodate poor conditions. Guides monitor weather forecasts daily via satellite and make all decisions about when to move based on conditions and team readiness rather than a fixed schedule.

How does Aconcagua compare to other Seven Summits objectives?

Aconcagua is considered one of the more demanding Seven Summits objectives due to its extreme altitude and unpredictable weather. The technical difficulty is moderate, similar to a glaciated peak like Rainier, but the elevation and duration of the expedition make it a serious undertaking. Climbers pursuing the Seven Summits typically consider Aconcagua a major step up from Kilimanjaro.

Staying Connected

How will I be able to stay connected with those at home?

We suggest bringing a smart phone or a WIFI-enabled device and using it where WIFI and internet services are available, as in Mendoza. While on the mountain, Starlink is usually available at both trek camps, Base Camp, Camp 2 and Camp 3. Cell service is widely available across most of Argentina.

Should I bring a cell phone or a satellite phone?

Cell phone coverage is generally available in and around towns, but not on the mountain. If you'd like to make phone calls from the mountain, you will need a sat phone. Phone rental is available through Remote Satellite Systems International. Check with your cell phone carrier to see if they offer international coverage in Argentina and make sure you have the appropriate international plans and understand the associated rates. RMI carries a satellite phone with the group through the entire trip for emergency use.

Do iPhones function well at high altitude?

Yes. However, the cold can impact the battery life making it necessary for it to be charged a few times on the trip.

Is a Kindle or Nook practical on this trip?

Yes, but if you wish to take it up on the mountain you will certainly need to recharge it once in a while using a personal solar charger. We recommend downloading all of your desired books before arriving in Argentina.

Reviews

Climbers rated RMI with an average of 5 stars across 0 ratings

Climber reviews of the Aconcagua expedition consistently reflect what defines the experience: the quality of the guiding, the depth of the logistical support, and the singular achievement of standing on the highest point in the Western Hemisphere. Participants frequently highlight the organization of the expedition from Mendoza to the summit, the quality of food and camp facilities on the mountain, and the professionalism of both the RMI guides and the Grajales Expeditions staff. For many climbers, Aconcagua is the expedition that redefines what they thought they were capable of at altitude.

There was nothing to im[prove. Dominic is my standout thought. He made the whole thing work.. The guides worked tirelessly. Have to adjust our trip to avoid mudslides in the Relinchos turned out really well. I would suggest considering remaining with the 360

The local staff, logistical support and meals provided by Grajales was excellent. The RMI guides were competent and supportive but didn't "handhold/babysit" the climbers.

Everything from the time I left home until I returned home! It would be really tough to say what part of it was the best. I guess getting to the high point for me and the long expedition were such cool experiences.

Our participants and guides were the best ever. I feel very blessed--many of them will continue as friends and climbing colleagues. I would do a trip led by Mark Tucker anytime. He has a very special way that I very much appreciated on a challenge such as this. Hannah and Avery were absolutely amazing and so helpful and patient! I would really love to climb with and learn from them on a future trip as well. I am impressed and amazed at these guides and all that they do!

The entire trip was great, from Mendoza to the summit and back. In thinking back on the trip, there were some great team members and we were lucky with the weather and the mountain, but what really put the icing on the cake was the guide team. They just simply made things fun, period.

Aconcagua

This program was much harder than expected and harder than almost any mountain I've climbed. I'd not hesitate to recommend participants complete a winter skills clinic or a Rainier summit before attempting this mountain as it's quite a mountain and you don't get close to the summit day experience while in the valley or on the upper mountain approach days so the summit push can come as a huge surprise to folks.
