About Us

Leave the Boys behind is a program started by Aspen Alpine Guides, an Aspen based professional guide Service. Aspen Alpine Guides has been providing quality mountain guiding adventures year-round in Aspen, Colorado since 1987. AAG creates adventures including guided summer and winter trips that include hiking, rock climbing, mountaineering, snow-shoeing, cross country ski instruction and tours, backcountry skiing, out of bounds lift assisted skiing, mountain biking, backpacking, hut trips on the 10th Mountain Hut System, and High Altitude Training for runners and Cyclists. We specialize in creating custom backcountry adventures for individuals and groups of all abilities and sizes. 

The Leave the Boys Behind program was started with the intention of creating an all-female experience in and around the pristine wilderness and rugged mountains of Aspen, Colorado. Our goal is to include females of all ability levels and ages in organized adventure that encompass a wide variety of sports. The drive to create Leave the Boys Behind stems from our desire to host outrageously fun experiences in the wilderness where the pressure from the boys is left at home. 

Aspen Alpine Guides and Leave the Boys Behind are equal opportunity service providers and employers that operate under a special use permit from the USDA Forest Service, White River National Forest.
