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.

New For Winter

Aspen Alpine Legacy Ski Tour

10th Mountain Division Hut Association and Aspen Alpine Guides are offering the 2015 Legacy Ski Tour from January 22nd to 25th. The Legacy is unique in that it is a multi-hut tour that covers remote wilderness terrain seldom used by individuals or groups. The tour is designed to celebrate the history of a few of the founding members of the association. The tour starts in Aspen with overnight stays starting at the Benedict Huts, continuing to the McNamara Hut and participants will close out the tour with a stay at Margy’s Hut leading to a final day ski descent into the very small town of Lenado with a short drive back to Aspen with AAG.
