Tools, resources, and volunteer opportunities to take care of our natural resources, and the places we go to play.

As a trailblazer in preserving Colorado’s outdoor spaces, conservation education and activism has always been essential to our mission. Yet never has protecting where we recreate been so relevant and vital to so many people. Our population is swelling. Technology is changing the landscape. And our community needs are evolving rapidly.

To transform a tradition of enhancing conservation programs across the state, the Colorado Mountain Club is building greater capacity, tools, and networks to promote sustainable, human-powered recreation, protect wild lands, and create and maintain access to the outdoor spaces that hold so much meaning.

Through data collection, advocacy, and stewardship, the CMC works to help balance human impact with natural resource conservation on public lands all over Colorado for generations to come. Join our cause—and our community.
