Over the course of three nights and four days you will experience the beautiful Colorado backcountry during a guided ski-tour stretching between Eagle and Aspen, Colorado.

AIARE Level 1: Sangree Hut Based

AAG has partnered up with the 10th Mountain Division Hut to offer Level I Avalanche courses in the ideal backcountry learning environment. These three-night, three-day courses enable all participants to experience backcountry conditions within the 10th Mountain Hut system by using the backcountry huts as a base for the course and fieldwork. 

Backcountry Skiing, Hut Trips

Colorado's extensive hut system offers the ultimate backcountry winter experience. Snowshoe, AT or telemark ski  into one of these rustic huts, for one night or for many. Our guides can assist with trip itineraries that suit your needs, skills and comfort levels ranging from a single overnight to multiple days out at either established huts or self-made winter camps.
