The Potomac Appalachian Trail Club (PATC) is a 100% Volunteer-Supported 501c3 non-profit  formed in 1927 for the purpose of building and maintaining the Appalachian Trail (AT), a 2190-mile footpath from Maine to Georgia, the longest hiking-only trail in the world.   We were the 1st club of the now 31 clubs who preserve the AT & its side-trails from Maine to Georgia. 

We are the Trail Guardians for over 1000 miles of trails in Pennsylvania, Maryland, West Virginia & Virginia, including 240 miles of AT.  Our territory begins in Central Pennsylvania at Pine Grove Furnace, continues thru Maryland & West Virginia to Harpers Ferry and extends into the mid-point of Virginia, including the Shenandoah National Park.  In addition, we maintain other regional trails, for a total of over 1,000 miles of trails, 1,000 acres of land and more than 80 shelters and cabins.
