The Appalachian National Scenic Trail, generally known as the Appalachian Trail or simply the A.T., is a marked hiking trail in the Eastern United States extending between Springer Mountain in Georgia and Mount Katahdin in Maine. The trail is about 2,200 miles (3,500 km) long, though the exact length changes over time as parts are modified or rerouted.
It is maintained by 31 trail clubs and multiple partnerships, and managed by the National Park Service, United States Forest Service, and the nonprofit Appalachian Trail Conservancy. The majority of the trail is in forest or wild lands, although some portions traverse towns, roads and farms. It passes through 14 states: Georgia, North Carolina, Tennessee, Virginia, West Virginia, Maryland, Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, New Hampshire, and Maine.
