About Aspen Expeditions
Aspen Expeditions is a professional mountain guide service that has been operating out of Aspen since 1977, offering four-season technical instruction and guided adventures in the Elk Mountains and beyond. Founded by AMGA-certified guides, the company has built nearly five decades of expertise in rock climbing, ice climbing, backcountry skiing, and alpine mountaineering — making it one of the most established guide services in the Colorado Rockies. Their base at Aspen Highlands puts them close to some of the most dramatic alpine terrain in the state.
The winter programme centres on backcountry skiing and avalanche education. Guided ski touring trips access the legendary powder stashes surrounding Aspen, from Montezuma Basin to the 14ers of the Elk Range. Multi-day hut trips along the 10th Mountain Division Hut system are a signature offering, combining backcountry skiing with overnight stays in high-alpine shelters. Avalanche safety courses at Level 1 and Level 2 are taught throughout the season. In summer, the guide team pivots to rock climbing instruction on Independence Pass and the Maroon Bells, ice climbing on the high-altitude routes above Ashcroft, and mountaineering expeditions to the summits of Capitol Peak, Pyramid Peak, and the other 14ers that ring the valley.
What sets Aspen Expeditions apart is the calibre of their guides. Many hold full AMGA or IFMGA certifications — the highest professional standard in North American mountain guiding. This means clients are learning from and climbing with some of the most qualified guides in the country. Whether you are a beginner looking to learn the basics of rock movement or an experienced mountaineer planning a technical summit bid, Aspen Expeditions brings the expertise and safety protocols to match the ambition. For adventure seekers who want to go beyond the groomed runs and into Aspen's wild alpine heart, this is the guide service to call.
