Mountaineering is where RMI started, and it's still the core of what we do. From a first summit of Mount Rainier to technical objectives across the Cascades, Alaska, and beyond, every program is built on the same guiding standards that have defined RMI since 1969.
Whatever your experience level, there's a mountaineering program built for where you are and where you want to go next.
RMI's mountaineering programs span the full range of the sport: single-day climbing schools, multi-day summit climbs, technical routes on Rainier's less-traveled faces, and expeditions on peaks across the Pacific Northwest, Alaska, and internationally. Every program is led by guides who climb these routes season after season, and every itinerary is built around real mountain judgment, not just getting to the top. Browse by location and route below to find the objective that's right for you.

Mountaineering
A five-day, expedition-style ascent of Mount Rainier via the Kautz Glacier for climbers seeking a technical route without added instruction.

Mountaineering

Mountaineering
Spend more time on Mount Rainier’s classic route with added flexibility for the best summit window.

The classic climb of Mt. Rainier

RMI guides classic and technical mountaineering routes across the Pacific Northwest, Alaska, and beyond. If it's a real objective, we can build a program around it.
It depends on the program. Entry-level climbs like Mount Rainier's standard routes are open to climbers with solid fitness and no prior mountaineering experience — RMI's guide team teaches the skills you need in the field. More technical objectives require prior glacier travel or roped-climbing experience. Each program page lists its specific prerequisites.
A mountaineering program is built around reaching a specific summit or completing a specific route. A skills seminar is built around learning technique — crevasse rescue, glacier travel, rope work — without the pressure of a summit attempt. Many climbers take a seminar before attempting a bigger mountaineering objective.
Guide ratios vary by program and terrain, typically ranging from 2:1 to 4:1 climbers per guide. More technical or remote objectives run tighter ratios. Each program page lists the specific ratio for that route.
Mountaineering is physically demanding regardless of technical difficulty — expect to carry a loaded pack over long days at altitude. RMI provides program-specific training guidance once you register, and our difficulty guide can help you gauge what a given route actually demands.
Yes. Many climbers pair a skills-focused program with a summit climb, or combine two objectives in the same region on one trip. Contact RMI directly to discuss building a custom itinerary.
Guiding, group camping and technical equipment, and permits are standard across RMI mountaineering programs. Personal gear, travel to the trailhead, and lodging outside of the program are typically not included. Each program page has a detailed inclusions list.
