High Country Adaptive Sports is a 501(c)(3) non-profit organization founded in 2015 by a passionate group of outdoor enthusiasts who recognized a barrier to entry for people with disabilities when it came to experiencing Arizona’s mountains, forests, and waterways. With the belief that we can all benefit from outdoor recreation, regardless of physical or cognitive challenges, our program has grown into a year-round operation in hiking, kayaking, rock climbing, mountain biking, and snow sports.

There is no limit to what can be accomplished when we work together. We are honored to guide our athletes on their expedition as they forge ahead, leaving behind perceived limits and discovering new destinations of potential within themselves.


That is our mission and that is what our staff and volunteers believe in.

We facilitate recreational activities for all people of all abilities. HCAS believes in the power and benefits of outdoor recreation and is creating a community where everyone has equal access to enjoy the best Northern Arizona has to offer!
