HMI is both an academic school and a wilderness programs provider. As a fully-accredited independent school, HMI brings high school juniors and seniors from all over the world to our campus in Leadville, Colorado for a single semester of place-based academics and wilderness expeditions.
In this environment, students can connect with their best self and become more engaged learners, community members, and citizens.
As a summer programs provider, HMI offers courses for middle and high school students with an emphasis on backpacking in the Colorado Rockies, intellectual inquiry, and experiential education-all to spark a desire for exploration and growth, and to set students on a path of self-discovery.
Finally, as a Gap Year provider, HMI leads high school graduates on three-month traveling courses through Patagonia and the American West where students pursue outdoor adventure while gaining experience in the field of environmental conservation.
