Pennsylvania's nickname is "Rocksylvania," but it’s not all rocks.
The A.T. in Pennsylvania is famed for its rocky terrain, especially on the long, flat ridges north of the Susquehanna River. The southern part of the state offers some of the gentlest, smoothest terrain of the entire A.T., including the Cumberland Valley. Other highlights are the A.T. Museum in Pine Grove State Park (home to the “half gallon challenge near the Trail’s mid-point) and the charming town of Boiling Springs, which houses ATC’s mid-Atlantic office. Flat, rocky ridges broken by steep descents to rivers and gaps characterize the A.T. north of the Susquehanna.
