The Appalachian Trail is the world's longest continuous footpath, running 2,167 miles from Springer Mountain in Georgia to Mount Katahdin in Maine. The trail passes through fourteen states, two national parks, and eight national forests. Hikers are able to walk through the Unakas and the Great Smoky Mountains of North Carolina; the Blue Ridge Mountains from North Carolina to Pennsylvania; the Catskills in New York; and over the crests of the White and Green Mountains, and the Berkshires of New England. The highest point is at an elevation of 6,000 feet.
Volunteers constructed the trail from 1922 until 1937 and continue to maintain it. In 1968 the trail became a part of the National Park System and is now called the Appalachian National Scenic Trail. At a pace of 14 miles per day, the entire hike takes 5 months.
