The United States Forest Service and the [[National Park Service]] are the primary agencies responsible for maintaining the Appalachian trail. The Trail runs through more than 75 different federal and state forests. Much of the trail is maintained by National Park Service Rangers who are assisted by the [[Appalachian Trail Conservancy]], a nonprofit organization dedicated to the protection and management of the trail, and by many civilian volunteer groups who donate their time towards keeping the park lands and trail maintained.<ref>http://www.nps.gov/appa/</ref> There is no charge to hike the rail, and hikers are provided with free lodging in the form of simple three sided shelters, each spaced about a day's journey apart.<ref>http://www.trailplace.com/</ref> | The United States Forest Service and the [[National Park Service]] are the primary agencies responsible for maintaining the Appalachian trail.
