Appalachian Trail Conservancy

We are the stewards of the world’s longest hiking-only footpath, the Appalachian Trail (A.T.). Completed in 1937, the A.T. is a unit of the National Park System. It is managed under a unique partnership between the public and private sectors led by the Appalachian Trail Conservancy. Established in 1925, the Appalachian Trail Conservancy (ATC) leads the effort to protect, maintain and celebrate the A.T. The ATC is largely funded by its more than 42,000 members and over 600,000 supporters located throughout all 50 states and in more than 15 countries.
