Inspiring Girls Expeditions has been empowering young women to lead and succeed through challenging wilderness expeditions that interweave science, art, and backcountry experiences for nearly 20 years. At the core of our work are our tuition-free, field-based summer expeditions for high school girls. In 2018, Inspiring Girls partnered with the University of Colorado Boulder to launch Girls on Rock, an expedition that explores the high alpine crags of Colorado’s Rocky Mountains. Girls on Rock is led by an instructor team of professional women scientists, artists, and wilderness guides who serve as mentors and models of peer support and collaboration. In 2019, Inspiring Girls Expeditions will run six expeditions in North America, including Girls on Rock, and two expeditions in Switzerland.
