Leave the Boys Behind is a female-specific, program offered by Aspen Alpine Guides. This program is designed with the intention of creating an all-female experience in and around the pristine wilderness and rugged mountains of Aspen, Colorado. Leave the Boys Behind will host trips throughout the year that include skiing, snowboarding, mountain and road biking, trail running, backpacking, peak climbs, avalanche courses, and international treks. All trips are lead by professional female guides.

Leave the Boys Behind is designed specifically for women, by women. Our goal is to include females of all ability levels and ages in organized adventures that encompass a wide variety of sports. The drive to create Leave the Boys Behind stems from our desire to host outrageously fun experiences where the pressure from the boys is left at home.
