The Appalachian National Scenic Trail is a 2,158-mile (3,480.6 km) footpath along the ridge crests and across the major valleys of the Appalachian Mountains from Katahdin in the central Maine wilderness to Springer Mountain in a designated wilderness area in north Georgia. The trail traverses Maine, New Hampshire, Vermont, Massachusetts, Connecticut, New York, New Jersey, Pennsylvania, Maryland, West Virginia, Virginia, Tennessee, North Carolina and Georgia. Primary use is by weekend or short-term hikers. "Thru-hikers" generally start from the South in early spring and hike the entire length in 5 to 6 months.

The Appalachian Trail Conference developed the trail and maintains it today through 33 affiliated volunteer trail clubs, in a cooperative agreement with the National Park Service. The Trail is the first completed unit of the National Trails System established by Congress and the President on Oct. 2, 1968; initiated by volunteers in October in 1921 and completed by volunteers on Aug. 14, 1937. More than 98% of the Trail is now on public land. The trail runs through 6 units of the National Park Service, 8 national forests and 60 state parks and forests.
