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.[1] The trail is approximately 2,200 miles (3,500 km)[a] long.
Trail hikers who attempt to complete the entire trail in a single season are called "thru-hikers"; those who traverse the trail during a series of separate trips are known as "section-hikers". ‎- Hattori Hanzo
