The Appalachian Trail is a 2,184 mile long public footpath that traverses the scenic, wooded, pastoral, wild, and culturally resonant lands of the Appalachian Mountains. Conceived in 1921, built by private citizens, and completed in 1937, today the trail is managed by the National Park Service, U.S. Forest Service, Appalachian Trail Conservancy, numerous state agencies and thousands of volunteers.
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 precise length of the trail changes over time as trails are modified or added. The total length is approximately 2,200 miles (3,500 km). The trail passes through the states of Georgia, North Carolina, Tennessee, Virginia, West Virginia, Maryland, Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, New Hampshire, and Maine. The path is maintained by 30 trail clubs and multiple partnerships, and managed by the National Park Service and the nonprofit Appalachian Trail Conservancy. The majority of the trail is in wilderness, although some portions traverse towns, roads and cross rivers.
The Appalachian Trail is famous for its many hikers, some of whom, called thru-hikers, attempt to hike it in its entirety in a single season. Many books, memoirs, web sites and fan organizations are dedicated to this pursuit.
An unofficial extension known as the International Appalachian Trail continues north into Canada and to the end of the range, where it enters the Atlantic Ocean, whereas unofficial extensions heading south into Florida create what is known as the Eastern Continental Trail.
The Appalachian Trail, the Continental Divide Trail, and the Pacific Crest Trail form what is known as the Triple Crown of long distance hiking in the United States.
The trail was conceived by Benton MacKaye, a forester who wrote his original plan shortly after the death of his wife in 1921. MacKaye's idea detailed a grand trail that would connect a series of farms and wilderness work/study camps for city-dwellers. In 1922, at the suggestion of Major William A. Welch, director of the Palisades Interstate Park Commission, his idea was publicized by Raymond H. Torrey with a story in the New York Evening Post under a full-page banner headline reading "A Great Trail from Maine to Georgia!" The idea was quickly adopted by the new Palisades Interstate Park Trail Conference as their main project.
On October 7, 1923, the first section of the trail, from Bear Mountain west through Harriman State Park to Arden, New York, was opened. MacKaye then called for a two-day Appalachian Trail conference to be held in March 1925 in Washington, D.C. This resulted in the formation of the Appalachian Trail Conference (now called the Appalachian Trail Conservancy).
A retired judge named Arthur Perkins and his younger associate Myron Avery took up the cause. In 1929, Perkins, who was also a member of the Connecticut Forest and Park Association and its Blue Blazed Trails committee, found Ned Anderson, a farmer in Sherman, Connecticut, who took on the task of mapping and blazing the Connecticut leg of the trail (1929–1933). It ran from Dog Tail Corners in Webatuck, New York, which borders Kent, Connecticut, at Ashley Falls, 50 miles (80 km) through the northwest corner of the state, up to Bear Mountain at the Massachusetts border. (A portion of the Connecticut trail has since been rerouted [1979–83] to be more scenic, adhering less to highways and more to wilderness, and includes a Ned K. Anderson Memorial Bridge.)
Anderson's efforts helped spark renewed interest in the trail, and Avery (leading the charge since Perkins’ death in 1932) was able to bring other states on board. Upon taking over the ATC, Avery adopted the more practical goal of building a simple hiking trail. He and MacKaye clashed over the ATC's response to a major commercial development along the trail's path; MacKaye left the organization, while Avery was willing to simply reroute the trail. Avery reigned as Chairman of the ATC from 1932 to 1952 (he died that same year).
Avery became the first to walk the trail end-to-end, though not as a thru-hike, in 1936. In August 1937, the trail was completed to Sugarloaf Mountain in Maine, and the ATC shifted its focus toward protecting the trail lands and mapping the trail for hikers.
In 1948, Earl Shaffer of York, Pennsylvania, brought a great deal of attention to the project by completing the first documented thru-hike. Later Shaffer also completed the first north-to-south thru-hike, making him the first to do so in each direction. In 1998 Mr. Shaffer, nearly 80 years old, again hiked the entirety of the trail, making him the oldest person ever to complete a thru-hike.
In 1994, a story appeared in the Appalachian Trailway News describing a 121-day Maine to Georgia thru-hike in 1936 by six Boy Scouts from the Bronx. Although the story has been accepted by some members of ALDHA, a great deal of doubt has also been expressed and this earlier thru-hike has never been verified. Shaffer's 1948 journey is still generally recognized as the first A.T. thru-hike.
In the 1960s, the ATC made progress toward protecting the trail from development, thanks to efforts of politicians and officials. The National Trails System Act of 1968 designated the Pacific Crest Trail and Appalachian Trail as the first national scenic trails and paved the way for a series of National Scenic Trails within the National Park and National Forest systems. Trail volunteers worked with the National Park Service to map a permanent route for the trail, and by 1971 a permanent route had been marked (though minor changes continue to this day). By the close of the 20th century, the Park Service had completed the purchase of all but a few miles of the trail's span.
