Southern Off Road Bicycle Association is a nonprofit organization focused on recreation, sports, leisure, or athletics. It is based in Roswell, GA. It received its nonprofit status in 1901.

Since 1989, SORBA has worked to create, enhance, and preserve great mountain experiences in the Southeastern United States.

**Support Trails. Support Community.**

At SORBA, we believe everyone should have access to the mental, physical, and social benefits that mountain biking provides. Every trail we help build, maintain, and advocate for is a step toward stronger communities, healthier people, and more connection with the outdoors.

Your donation helps power this mission across the Southeast—fueling local chapters, supporting volunteers, and expanding access to public lands through sustainable trail systems.

Whether you ride, hike, run, or simply believe in the value of outdoor spaces, your support makes a lasting impact.

**Donate today and be a part of the movement to build trails and community—together.**
