For more than 40 years, TOSC has advocated for and cared for the parks, trails, and open spaces of Colorado’s Southern Front Range. Through hands-on stewardship, community programs, and a mission to build the next generation of outdoor advocates, we make sure everyone has access to the outdoors, today and for years to come.
The outdoors gives us more than trails, it gives us solitude, recreation, and connection. It also brings us together. We protect these places because they strengthen our community, whether it’s a family hike, a child’s first time in nature, a quiet moment when the world feels like too much, or neighbors coming together to care for the land we all share.
This year, we’re transforming our new headquarters at 627 S 31st Street into a community hub, a gathering place for the outdoor community in the Pikes Peak region. With continued support, we’ll also be expanding our Marlow webtool, grow our One Bag Challenge and continue to inspire new advocates.
Did you know that since 2024, TOSC has led 130+ cleanups with 1,100+ volunteers and picked up over 8,000 lbs. of litter.
“"I went to my first One Bag Challenge cleanup expecting to pick up trash for an hour and go home. What I didn't expect meeting so many wonderful people. We laughed and got to know each other. I left with three new friends and a bond to our park that I would have never had without TOSC."” — TOSC Volunteer during the Sand Creek Trail Cleanup.
