The Appalachian National Scenic Trail, often called the Appalachian Trail or the A.T., is a hiking trail on the Appalachian Mountains in the eastern United States.
The Trail runs from Georgia to Maine and is around 2,200 miles (3,500 km) long. The exact length changes over time as parts are changed.[a] It passes through 14 different states.
The Appalachian Trail Conservancy says the Trail is the longest hiking-only trail in the world.[1][2] More than two million people hike part of the trail at least once each year.[3]
