Appalachian Trail 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. The trail is about 2,200 miles (3,500 km) long, though the exact length changes over time as parts are modified or rerouted. The Appalachian Trail Conservancy claims that the Appalachian Trail is the longest hiking-only trail in the world. More than 2 million people are said to do at least one day-hike on the trail each year.

The recreation area is on the east side of the mountain and is part of the Yakima Indian Reservation and includes the popular Bird Creek Meadows area.
