This Season

Aspen Alpine Guides offers guided alpine activities for spring, summer, winter and fall. Click on the left tabs for our full Winter or Summer descriptions. We also offer a series of international trekking and climbing trips, as well as American Institute for Avalanche Research and Education (AIARE) courses. 

In addition to general AAG programs we are happy to have several cross-over ski instructors who are able to teach through the Ski and Snowboard Schools of Aspen / Snowmass. These instructors have medical certifications as well as avalanche training and are available for both kids and adults. Lessons take place on-mountain, in the side country, in the backcountry or a combination that results in Lift-Served Side-Country skiing or boarding.
