The Appalachian Trail (AT) is a continuous, marked footpath extending along the Appalachian Mountain system for more than 2,100 miles between Katahdin, a granite monolith in the central Maine wilderness, and Springer Mountain in Georgia.
From the south the AT enters Pennsylvania near Pen Mar in Franklin County, proceeds generally northward for about 85 miles, crosses the Susquehanna River north of Harrisburg, then heads east toward New Jersey, leaving Pennsylvania near Delaware Water Gap.
The trail is marked with white blazes.
