http://www.appalachiantrail.org/The Appalachian Trail is designed, built, and maintained by hikers for foot travel. Motor vehicles are illegal on all off-road sections of the Appalachian Trail. >Bicycles and mountain bikes are not permitted except where the A.T. coincides for about three miles with the C&O Canal towpath in Maryland, the Virginia Creeper Trail in Virginia, in certain Pennsylvania state gamelands, and roads in town. Horses, llamas, and other pack animals are not allowed on the A.T., except along the C&O Canal towpath in Maryland and on about 50 percent of the A.T. in the Great Smoky Mountains National Park (where, by law, the route is open for horses as a historical use).
