Vinson Massif

Vinson Massif

Located only 660 nautical miles from the South Pole, Vinson Massif (16,067') is the highest peak in Antarctica and one of the renowned "Seven Summits." 


  • Scale the "top of the bottom of the world" - the highest mountain in Antarctica and one of the most remote mountains on earth.
  • Fly across the Drake Passage and over the sprawling icy interior of Antarctica to reach Vinson Base Camp.
  • Climb Vinson with Dave Hahn, the most experienced and widely regarded Vinson guide in the world.
  • Improve your chances of reaching the summit with an itinerary that includes proper acclimatization and the flexibility to accommodate for the uncertainties of Antarctica’s weather.
  • Benefit from RMI’s excellent organization, support, and carefully planned and outfitted Vinson expedition: all the small advantages that add up to a more enjoyable experience.
  • Take part in an RMI adventure to Antarctica and see why we continue to set the standard in guiding excellence.

Climbed for the first time in 1966, Vinson still sees very few visitors and remains a pristine and majestic peak. To reach this remote area of the world, we fly from Punta Arenas, Chile and land on the blue ice runway of Union Glacier. A short flight then brings us to Vinson Base Camp at the foot of the Branscomb Glacier in the Ellsworth Mountains. From here we ascend the Branscomb Glacier and climb the headwall on Vinson, setting up two camps along the way. Summit Day is one of the most spectacular of any big climb in the world: as we ascend from our High Camp (12,400') the views of the immense ice sheets which surround the Massif gradually come into view, the final steep push up the summit ridge is exhilarating but not technically difficult, and standing atop this remote summit a climber looks for miles in all directions onto a landscape virtually untouched by humans.


When your goal is the highest peak on the Antarctic continent, experience matters. Rainier Mountaineering, Inc. was established in 1969 and is one of America’s oldest and most-trusted guide services. We are the largest guide service on Mt. Rainier and Denali and leaders in guiding climbs and treks around the globe. Our years of leading mountain adventures give us the experience and knowledge to create the best possible trips and we work hard to live up to our reputation as an industry leader. Nowhere is this more important than for an expedition to Vinson where the remote and inhospitable landscape necessitate that all the finer points are addressed. Our trip preparation before departure and when you return takes care of the details for you, from hotels to airport transfers, so that you can focus on preparing for the climb instead of the distraction that comes with coordinating logistics.

Our Vinson Massif expeditions are led by Dave Hahn and RMI’s foremost U.S. guides. Dave holds the world record for Vinson Massif - he has reached the summit an impressive 31 times.

Dave Hahn and RMI’s guides bring years of climbing experience on not only Vinson but on mountains all over the world, from the Andes to the Alaska Range to the Himalayas. As you reach higher elevations and test the limits of your experience, the value of an accomplished, highly trained RMI Guide held to our standards cannot be understated.


Safety has always been RMI’s top priority and we strive to create the safest mountain experience possible. RMI’s experienced team of guides focus on leading a fun and successful climb of Vinson without compromising safety. We apply the same standards of safety we bring to Alaska and the Himalayas to our climbs of Vinson. Careful planning, precise ascent profiles, flexibility in our itinerary, and diligent attention are taken as we venture to high altitudes. Additional resources are stationed at Base Camp and comprehensive medical kits, rescue equipment, and radio and satellite communication equipment are carried with the team throughout the climb.

As you prepare for your upcoming adventure please feel free to contact our office and speak directly to one of our experienced guides regarding equipment, conditioning, the route, or any other questions you may have about our programs. We are available Monday thru Friday 8:30 a.m. to 4:00 p.m. at (888) 89-CLIMB or info@rmiguides.com.

Travel Consultant

RMI has partnered with Pirjo DeHart to provide comprehensive travel support to Punta Arenas. As a Travel agent for CTT Destinations, she has booked countless miles for adventure travelers across the globe. Pirjo has worked with Vinson Massif climbers for many years and understands the travel needs of this program. Please call (425) 831-0367 or email Pirjo.DeHart@CTTDestinations.com.

Cancellation Insurance and Medical Evacuation

Due to the remote nature of this program, we require everyone to purchase a medical evacuation policy with minimum coverage of $500,000. Additionally, we encourage participants to consider travel insurance.

Medical Evacuation: An illness or injury in a remote area could require a medical evacuation costing well over $100,000. For this reason, we require everyone to purchase a medical evacuation policy with minimum coverage of $500,000. Travel insurance providers (such as AIG Travel Guard and Travelex Insurance) typically offer reimbursement for medical evacuations. Check with the insurance providers listed below for specific coverage details and options, including details of what constitutes a medical vs. a non-medical emergency.

We strongly encourage everyone to purchase travel insurance which can cover trip cancellation, interruption, delay, baggage loss or delay, medical expenses, medical evacuation, repatriation and more. Travel insurance offers the best possible protection in the event of a sudden, unexpected illness or injury prior to or when traveling. Note that many of the insurance options can be purchased under one policy but some coverage may only be available if purchased within 14 days of making your trip deposit or if purchased as an upgrade to an existing policy rather than as a stand-alone option.

Cancellation Insurance: Cancellation insurance offers protection of deposit and registration funds should you need to cancel from a program. This might be due to an injury during training, a personal illness, or it might be due to extenuating circumstances, such as family emergencies. Policies are determined based upon your home state, check with the insurance providers listed below for specific coverage details and options, including adventure/sports coverage*.

*Adventure/Sports Coverage: Most standard policies do not cover climbing or mountaineering. You can purchase Adventure/Sports Coverage as an upgrade to a standard policy. Please be sure to check with your provider and their description of coverage to make sure the policy you are purchasing provides you with adequate protection.

For more information, please visit one of the websites below or contact your local travel agent.

Travel Advisories / Warnings

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

Getting There

Climbers flying from the U.S. usually fly via Santiago, Chile and then onward to Punta Arenas, Chile (PUQ). The 5-hour flight to Antarctica is aboard a Russian Ilyushin Il-76 cargo plane which lands on a blue ice runway at Union Glacier. From Union Glacier we board a Twin Otter on skis for the one-hour flight to Vinson Base Camp. The logistical support needed to get climbers and their gear into position on Mt. Vinson is extraordinary.

Entry Information

A valid passport is required for your travels. Your passport must be valid for 6 months beyond the expected return date.

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.

If you are traveling under a non-U.S. passport, please check your country's specific requirements with the Chilean Embassy.


The Antarctic Treaty System that governs the continent dictates strict environmental protection practices and biosecurity guidelines exist for travel to Antarctica in order to prevent any alien species or diseases from accidentally being transported onto the continent. Before packing your bags, please clean and carefully inspect your gear to make sure that it is completely free of any soil, plant, or other organic material. Equipment will be checked again in Punta Arenas prior to departure. You will be provided with a "Biosecurity and Equipment Cleaning" document for further information.

Arranging Flights to and from Punta Arenas

Please arrive in Punta Arenas on Day 2 of the itinerary.

Airfare should be booked to depart Punta Arenas two weeks after the scheduled trip end. When you return to Punta Arenas, you can reschedule your return flight at the ticket counter or over the phone. Depending on the airline, a change of date penalty is usually charged at this time. We have found scheduling a future date works better than an open-ended ticket or missing an early return date.

Please make sure that you purchase a fully flexible airline ticket that allows for changes. Discount fare, air miles or frequent flier points are typically heavily restricted and with limited space availability and so can be the cause for many unwanted headaches at the end of the trip. Due to the extremely unpredictable weather the chances are very high that you will not fly on your regularly scheduled return flights, thus having flexibility is extremely important.

Here are some considerations when making your flight arrangements:

  • We are traveling during the region's high season, so seats to Punta Arenas can be limited and expensive.
  • In general, the cheaper your ticket, the more difficult and/or expensive it is to make changes on short notice. Some fares do not even permit you to fly stand-by.
  • Change fees can be expensive and payment is required at the time of change.
  • The RMI Office is available to help facilitate in re-booking the return flights if needed. When the group leaves Union Glacier, you can call our office and we can contact your travel agent to start the process of re-booking for you. If you would like us to change your ticket, we will need all your ticket and passenger information. If it is not a fully flexible ticket, then we will also need a credit card number and maximum amount we are allowed to charge for making the change.
  • Once you have confirmed your flights please forward your itinerary, flight details, confirmation number and/or ticket number to the RMI Office.

Airport Arrival

Upon arrival in Punta Arenas, take a taxi from the airport to our hotel, the Hotel Diego de Almagro.

Luggage for Flights to Union Glacier

All luggage must comply with international air transport regulations. White gas, fuels or other hazardous substances must not be carried on flights to Antarctica. No sharp objects (e.g., multi-tools, Swiss Army knives) should be carried in hand luggage. All cargo hold luggage and hand luggage will be screened by airport security personnel.

We have a baggage allowance of 50 lbs of personal gear for each team member. This includes all hold luggage but does not include the clothing that you will be wearing on the flight to Union Glacier. If the total weight of your personal gear is more than 50 lbs, you will be charged $30 per pound for any overages. The excess baggage fee must be paid in cash (no credit cards are accepted) prior to departure for Union Glacier. No individual bag can weigh more than 66 lbs (30kg). No exceptions.

In preparation for weighing and collection, your luggage should be separated into 4 categories:

  1. Clothing worn on flight to Antarctica: This will remain with you until your flight and should include various under-layers as well as your parka, rain pants, Antarctic boots, gloves, hat, goggles or sunglasses.
  2. Hand Luggage: Includes items you carry aboard in a reasonable sized daypack or on your person. Hand luggage includes your passport and other items that you want to keep with you until flight day or to have handy during the flight: all medications, cameras, sunscreen, and money. You MUST have your passport in your hand luggage. No sharp objects are allowed.
  3. Hold Luggage: Personal food, extra clothing and personal equipment for use in Antarctica, including knives and sharp objects. Hold luggage will be loaded the day prior to the flight and will remain in the hold of the plane until weather conditions permit us to fly to Union Glacier. Please tag your bags with traveler name, program code, and RMI. You will not have access to these items before or during the flight. Since weather delays are the norm, do not put anything in your hold luggage that you might need during your stay in Punta Arenas, including medications, perishable foods, passport, credit cards or cash.
  4. Left Luggage: City clothes and any other items you want to leave in Punta Arenas. These should be left at your hotel. Please make sure to tag all left luggage with both your name, as well as "RAAL" in case ALE needs to retrieve our luggage for us upon return from Antarctica. Please make sure you have an accurate description of the number and type of bags you have left in the hotel. This will allow ALE to move your bags to an alternate hotel if required on your return to Punta Arenas. Do not leave valuables in your left luggage.

When preparing your luggage for weighing keep in mind:

  • Your hold luggage will be weighed and collected from you the afternoon prior to your flight and you will not see it again until you arrive at Union Glacier.
  • You will pre-weigh hand luggage at the same time to ascertain its approximate weight and size and your group’s total luggage weight.
  • Your maximum personal baggage weight is 50 lbs. Weight above that limit will be subject to a $30 per pound charge –pack efficiently!

Immunizations & Travel Medicine

No immunizations are required for traveling in Chile, however, there are several recommendations. 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 from 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

Union Glacier Camp has a basic clinic where excellent care for minor illnesses and injuries is readily available. The clinic is staffed by a doctor and medic who specialize in emergency and remote medicine.

At Vinson Base Camp, a Base Camp Manager is available to coordinate an emergency response in the event of an accident on the mountain.

In the event of more serious illnesses or injuries, evacuation to Punta Arenas, Chile, would be required.

Antarctica Facts

Antarctica is the coldest, windiest, driest continent on the planet. In the winter, the lowest recorded temperatures (without wind chill!) have reached -89°C (-129°F). The continent averages 2.4 km in height (1.5 miles) above sea level, making it 1.5 km (almost a mile) higher than the global average land height! Each year the South Pole receives less than an inch of water ... in the form of snow, of course. This amount of precipitation is similar to that of another desert, the Sahara.

Vinson Massif, at 78°35'S, 85°25'W is 21km (13 miles) long and 13km (8 miles) wide, is the highest peak in Antarctica. It lies on the southern part of the main ridge of the Sentinel Range. It was named for Carl G. Vinson, a Georgia congressman and a major force in 20th century U.S. Antarctic exploration. Discovered in 1957 after being sighted by U.S. Navy aircraft, it was first climbed in December 1966 by a combined group from the American Alpine Club and the National Science Foundation.


Vinson's weather is generally controlled by the polar ice cap's high-pressure system, creating predominantly stable conditions, though high winds and snowfall are possible. Annual snowfall on Vinson is low, but high winds can cause accumulations and low visibility conditions. During the Antarctic summer (November through January), there are 24 hours of daylight. The average temperature during these months is −20°F.

For current conditions in Punta Arenas, Chile, check Weather Underground or Yr.no.

For current conditions at Union Glacier, Antarctica, check Yr.no.


Electricity in Chile is 220 Volts and 50 Hertz. Carry a universal convertor and plug adaptor travel kit.

There are limited charging facilities provided by ALE at Union Glacier. To access them you will need a 12V DC-DC charger for your device that is capable of plugging into a cigarette lighter socket. There are no charging capabilities available on Vinson and each climber is responsible for bringing their own necessary power supplies.


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

You should find that $600-$900 for spending money is adequate for restaurant meals, drinks and pocket money.

Credit cards are accepted in some stores, restaurants, and hotels in Punta Arenas, but it is still a good idea to bring some U.S. cash to exchange if necessary. We do not recommend bringing traveler's checks.

ATMs displaying "Redbank" work with Cirrus, MasterCard and Visa cards. Our hotel accepts Visa, MasterCard, American Express, and Diners Club International cards. Be sure to notify your credit card company before leaving home so that your account is not disabled due to the change in buying patterns.


Our guides work hard to ensure your well being and success on the mountain. If you have a positive experience, a gratuity is an excellent way to show your appreciation. Amounts are at your discretion and should be based on your level of enjoyment.


Lonely Planet and other travel service websites are readily available and describe Antarctica well.

Alfred Lansing's Endurance: Shackleton's Incredible Voyage to the Antarctic remains an enduring classic of exploration and survival on the Antarctic continent.

Physical Fitness Training


Mountaineering requires a high degree of physical stamina and mental toughness. Even for the healthiest and fittest individuals, climbing mountains qualifies as an extremely challenging endeavor.

  • Start immediately. Start a rigorous fitness and training program now with the goal of arriving in top physical condition and confident in your skills.
  • Be intentional. Focus on gaining the necessary strength, stamina and skills to meet the physical and technical demands of the climb.
  • Be sport-specific. The best fitness and training program mimics the physical and technical demands of your climbing objective. The closer you get to your program date, the more your training should resemble the climbing.

For Vinson, you are preparing for:

  • Steep climbing and glacier travel with a 50-60 lb load
  • A 10+ hour summit day
  • A trip to an extremely cold environment
  • Mountaineering techniques which require core strength and flexibility

Nothing ensures a personally successful adventure like your level of fitness and training. Bottom line: Plan on being in the best shape of your life and ready for a very challenging adventure!

Please refer to our Resources for Mountaineering Fitness and Training for detailed fitness and training information.


The key to climbing high is proper acclimatization. Our program follows a calculated ascent profile which allows time for your body to adjust to the altitude.

Excellent physical conditioning significantly increases your ability to acclimatize as you ascend. Climbers in excellent physical condition simply have more energy to commit to the acclimatization process throughout the days and nights of the ascent, allowing their bodies to adjust to the altitude more easily.

Finally, physical performance and acclimatization are also related to how well you have taken care of yourself throughout the hours, days and weeks prior to summit day. Arriving healthy and well-rested, maintaining proper hydration and caloric intake, and protecting against unnecessary heat loss (staying warm) are all key factors in an individual’s success on an expedition such as this.

What You’ll Need

The following is a list of required equipment. We may encounter a variety of weather conditions throughout our climb, including rain, wind, snow, sleet and extreme heat. Skimping on equipment can jeopardize your safety and success, so we want you to think carefully about any changes or substitutions you are considering. If you have questions regarding the equipment needed for your upcoming climb, give us a call and speak directly to one of our experienced guides.

Most of the required equipment is available for rent or purchase from our affiliate Whittaker Mountaineering. RMI climbers receive a 10% discount on new clothing and equipment items ordered from Whittaker Mountaineering. This offer excludes sale items.

Equipment List


      An 80-90 liter pack is the recommended size for this climb.  Your pack  must be large enough for your layers, climbing gear, and food, as well as a portion of your tent and group load (kitchen equipment). A separate summit pack isn't necessary.

    • DAY PACK

      A 25+ liter day pack to use as carry-on for flight to Antarctica, while traveling and sightseeing.


      A bag rated to -20° to -40° F. Either goose down or synthetic, with ample room for movement. Most guides prefer down, because it is lightweight and compactable. A waterproof bag is preferred, but not mandatory.
      The temperature rating system for sleeping bags is arbitrary and is not a guarantee of warmth. Base your selection on how well you do in the cold. If you tend to sleep on the cold side, choose a bag rated on the lower end of the temperature range. Using two sleeping bags together is not recommended.

    • ICE AXE

      The length of your axe depends on your height. Use the following general mountaineering formula: up to 5'8", use a 65 cm axe; 5'8" to 6'2", use a 70 cm axe; and taller, use a 75 cm axe. If you hold the axe so that it hangs comfortably at your side, the spike of the axe should still be a few inches above the ground.


      The 10 to 12 point adjustable crampons designed for general mountaineering are ideal. We highly recommend anti-bot plates to prevent snow from balling up underfoot. Rigid frame crampons designed for technical ice climbing are not recommended.


      A digital transceiver is preferred; analog will work as well. If you rent a transceiver, one set of new batteries will be provided.


      For traveling on fixed ropes. Most people prefer an ascender designed for their weak hand, leaving their strong hand free to hold their ice axe. For example, a right-handed person would use a left-handed ascender.


      You will need protective sunglasses, either dark-lensed with side shields or full wrap-around frames. Almost all sunglasses block UV-A, UV-B and infrared rays adequately. Pay attention to the visible light transmission. The darkest lenses (glacier glasses) only allow approx. 6% visible light to get through, while lighter lenses (driving glasses) let in as much as 20+ %. A good rule of thumb is that if you can see the wearer’s pupils through the lenses, they are too light for sun protection at altitude.

    • Each glove layer is worn separately as conditions change during the climb.


      Wind/water resistant, insulated gloves. These also serve as emergency back-ups if you drop or lose a glove.


      Medium weight insulated gloves for climbing and working around camp. These should be both durable and dexterous enough to allow you to perform activities like setting up or taking down tents while wearing them.

    • We recommend a minimum of five upper body layers, all of which can be used in conjunction with each other. Two of these should be insulating layers, one light and one medium, that fit well together. Today there are many different layering systems to choose from, including fleece, soft-shell, down and synthetic options.

    • We recommend a system of four layers, all of which can be used in conjunction with each other. Products which combine several layers into one garment, such as traditional ski pants, don’t work well as they don’t offer the versatility of a layering system.


      A new breed of composite boot like the Millet Everest or an expedition-style plastic double boot in combination with a full overboot is mandatory. Price is the best indicator. Though expensive, the function of footwear is of crucial importance. Select a brand's "top of the line" model and it should be sufficient. The boot needs to be roomy enough to allow for good circulation. Anticipate a sock combination when sizing them (single sock, liner and sock, or two heavy socks on each foot). Wear the boots as often as possible before the climb, to determine proper fit, comfort and performance. It is recommended that you keep your boots in your carry-on luggage for all of your commercial flights in case your luggage is mis-directed.


      Goose down or synthetic fill. Booties can be worn inside of the overboots while walking around camp, which allows an opportunity to dry out inner boots.


      A knee-length pair of gaiters, large enough to fit over your mountaineering boots, will be needed for protection from snow, mud, and catching your crampons on loose clothing. These are not necessary with all-in-one boot / gaiter models.


      We recommend small tubes of SPF 15 or higher, which can be carried in pockets for easy access and to prevent freezing.

    • MEALS

      See the Food tab for suggestions and quantities.


      Hard-sided, screw-top, one-liter water bottles with wide mouths are required. Plastics made with high post-consumer recycled content and BPA-Free are recommended.

Breakfast and dinner meals on the mountain are included as indicated in our Trip Itinerary. Most restaurant meals are on your own. Your trip fee does not included bottled water and drinks.

Mountain Lunches

You are responsible for your own mountain lunches for 16 days. Lunch items should weigh about 9 - 10 lbs.

You are packing two different kinds of food for this trip - "Mountain Lunches" and "General Snack Food".

Mountain Lunches are the snacks that you will be eating throughout the climb. The food is generally bought from the U.S. and it is your tried and true favorites. You will need to bring enough snack food for 10 days of "Mountain Lunches". Snack items should be small and compact (not bulky) and fit inside a stuff sack as you will be carrying these snacks with you while you climb.

General Snack Food is what you will be eating if we are delayed for any reason while on the ice. Most of this food can be purchased in Punta Arenas. It should be small and compact as well but we will be able to cache some of the food at Union Glacier and at Vinson Basecamp. You will need a total 6 days of General Snack Food.

Take lunch foods that you genuinely enjoy. Eating well is the key to maintaining your strength while in the mountains. And in order to combat the loss of appetite at altitude, it is best to have a variety of foods from which to choose, from sweet to sour to salty.

Lunch snacks are eaten during short breaks throughout the day while in the mountains. Avoid packing any items that require preparation or hot water.

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).

Keep in mind that upon arriving in Chile you must clear customs and food items are subject to inspection. Fresh fruits, vegetables, and meats are not allowed and will be confiscated. Please plan on buying such items in Punta Arenas, and understand that the selection in Punta Arenas is limited and the markets do not always carry the same foods as in the United States.  When going through Customs any food you do bring with you should be declared. 

Mountain Breakfasts and Dinners

The breakfast menu includes items such as instant oatmeal, cold cereals (granola), breakfast bars (Kashi, Kudos), hot drinks (coffee, tea, cocoa, cider).

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. There are limitations, but the menu is planned to offer good variety and ample portions.

Risk Management

Managing risk is RMI's number one priority. Our guides manage significant hazards inherent in mountaineering such as avalanches, ice fall, rock fall, inclement weather, and high winds, but they cannot eliminate them.

Please clearly understand that mountaineering is inherently a hazardous sport. You are choosing to engage in an activity in which participants have been injured and 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 risk and hazards of mountaineering, and make their own choices about whether or not to engage in this activity.

Climber Responsibilities

Mountaineering is both an individual challenge and a team endeavor. Some of the responsibility for the team is carried by the individual climbers. For this reason, we ask that each participant:

  • is physically and mentally fit, properly attired and equipped, and continues to self assess throughout the program to ensure as safe a climb as possible. If a climber’s own physical fitness limits his or her ability to safely continue upward, that can have a negative impact on the summit experience or opportunity of other climb participants.
  • honestly and accurately describe themselves, in terms of fitness, health and skills, and their equipment to their guides, and that they adhere to the advice of their professional mountain guide.

Age-Appropriate Guidelines & Restrictions

RMI adheres to the following age-appropriate guidelines and restrictions on all climbing programs, domestic and international.

  • Ages 15 & under: No participants age 15 & under
  • Ages 16 & 17: Accompanied by parent or legal guardian
  • Ages 18 & above: No restrictions 

An individual’s birthday must precede the departure date of the program. For example: a 15 year old who turns 16 on July 1 may participate on a program beginning July 2.

Accompaniment by parent or legal guardian is required for the program or climb.

Under-aged participants on Private Climb programs are assessed on an individual basis.

Summit Attempt

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 party may have to turn around 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, avalanche hazard, team dynamics, etc.), are not Rainier Mountaineering, Inc.’s responsibility and will not result in refund or reschedule.

General Policies

Any Participant under the age of 18 must be accompanied on the trip by a parent or legal guardian and both the Participant and parent or legal guardian must sign all forms.

RMI's program plans and itineraries are subject to change or adjustment based on a number of factors. These include, but are not limited to, route conditions, weather, terrain, and many other factors. RMI has complete discretion to change plans to accommodate any of these or other factors, including discretion to change program schedule or itinerary, and change guides or staff, as necessary for the proper and safe conduct of the program.

We reserve the right to cancel any program due to inadequate signups, weather or route conditions. In such a case, a full refund is given; however, RMI cannot be responsible for any additional expenses incurred in preparing for the program (i.e., airline tickets, equipment purchase or rental, hotel reservations).

If the Participant decides to leave a trip at any time after the start of the trip and prior to its conclusion, he or she will not be entitled to a refund.

RMI reserves the right to dismiss the Participant from a trip or to send the Participant to a lower altitude at any time if RMI determines, in its sole discretion, that the Participant is not physically, technically, or psychologically prepared for or capable of participating in the program.

The Participant understands and agrees that RMI assumes no responsibility or liability in connection with any travel and hospitality service provided to the Participant by others in connection with the trip, including but not limited to the services provided by airlines, hotels, and motor vehicle operators, and that 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.

RMI recommends and strongly advises that the Participant have or purchase personal life, medical, accident, travel, baggage, trip cancellation, and other insurance that may pertain to participation in the program. The Participant understands that RMI provides no such insurance coverage in connection with the trip.

When should I book my return flight?

Airfare should be booked to depart Punta Arenas two weeks after the scheduled trip end. When you return to Punta Arenas, you can reschedule your return flight at the ticket counter or over the phone. Depending on the airline, a change of date penalty is usually charged at this time. We have found scheduling a future date usually works better than an open-ended ticket or missing an early return date.

How long is the flight from Punta Arenas to Union Glacier? How far from Union Glacier to Vinson Base Camp?

The flight to Union Glacier, Antarctica requires approximately five hours. The flight, crossing Drake Passage and the Antarctic Circle, is aboard a Russian Illuyshin cargo plane and lands on a blue ice runway at Union Glacier.

If the weather allows, we will continue for the one-hour flight on a Twin Otter ski-equipped plane to Vinson Base Camp, located at 7,200' on the Branscomb Glacier.

Is a down suit is necessary?

A down suit is not necessary, though a few climbers do prefer it. For most climbers, an 8,000-meter down parka with attached hood in combination with 8,000-meter down pant is the preferred option because it offers the most versatility when climbing.

Why no headlamp?

Vinson is located very near the South Pole and thus, during the southern hemisphere summer, the sun will be above the horizon 24 hours a day.

Will I need to pull a sled?

Typically the guides and a few (not all) climbers will pull sleds.

Will we see penguins? I've heard that Antarctica is teeming with animals. Will there be any wildlife?

Penguins can be seen near Punta Arenas. Should there be a flying delay to the continent, we can make time for an outing to view them.

While the coast of Antarctica is a popular cruising destination because of the wildlife, the interior part of the continent is significantly colder and thus is devoid of all life. While an odd, lost bird may make an appearance from time to time as it passes through the Ellsworth Mountains, the Vinson Massif is nearly a sterile environment, hundreds of miles from the continent's edge and even farther from open water.

How cold will it be?

At Union Glacier, temperatures might hover around 0 to +20 F, but there will be shelter available. At Vinson Base, the temperatures will likely be -10 to +10 F. On a typical summit day, temperatures are likely to range from -35 F to -20 F. If the wind is not blowing and the sun is shining, summit temperatures can be surprisingly comfortable. Most of our climbing activities are planned so as to take advantage of the sun's rays. While the sun is not setting on Vinson during the climbing season, it does creep behind the mountain from time to time.

How hard is the climb?

The climbing itself is similar to the glaciated terrain one encounters on either Denali or Mt. Rainier. Packs are generally lighter than on a typical Denali trip, but heavier than for an alpine-style ascent of Rainier. What makes Vinson difficult are the cold temperatures and the remote location. Many experienced climbers are surprised by the difficulty of summit day. This is partly because summit day is long and cold and at high altitudes.

Why does this expedition cost so much?

The logistical complications of such a trip are profound. Consider what it takes to station aircraft, personnel and fuel at such odd places on the planet. Then consider what it takes to do the same thing safely and in an environmentally friendly manner. Many have presumed that the costs for such a trip would come down through the years, but the reality is that such costs generally rise.

What is the food like on the mountain?

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

What is the pace like?

We travel at an appropriate speed to cover the distance we need for the day without going too quickly or too slowly. While the actual distances are relatively short, the altitudes to which we travel are high and the climbing can be very challenging. The adventure as a whole, and certainly the days when we are carrying heavy loads, is generally characterized as strenuous.

What are the toilets like?

At Union Glacier, there are enclosed toilet facilities. At Vinson Base Camp, there are outdoor latrines. On the mountain, solid waste is captured in W.A.G. (waste alleviating gel) bags while liquid waste is concentrated in "pee-holes" in designated areas. This necessitates the use of pee bottles while climbing and transporting your liquid waste to the nearest disposal site.

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

Antarctica is the most remote continent on earth. It should not be expected to remain in constant contact with your home without incurring significant cost. At Union Glacier, you can purchase minutes to use on an ALE supplied satellite phone. On the mountain, you will have to arrange to bring your own personal satellite phone. RMI guides carry a satellite phone for emergency use.

Should I bring a cell phone, smart phone or a satellite phone?

A satellite phone is the only way to send/receive calls and data on the continent of Antarctica. Satellite phone rental is available through Remote Satellite Systems International.In Punta Arenas, a cell phone set up for international use will work.

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.
