The Susquehannock Trail System (STS) is an 83.4-mile (134.2 km) loop hiking trail in Susquehannock State Forest in Potter County (with a few short segments in Clinton County) in north-central Pennsylvania, United States. The trail walks through two state parks and passes near three more state parks. It also traverses Hammersley Wild Area, the largest area in Pennsylvania without a road. The loop is supplemented by two cross-connector trails, several short access trails, a shared path with the Donut Hole Trail, and two connectors to the Black Forest Trail. The STS is the oldest backpacking trail in Pennsylvania, and has been noted for its solitude while traversing remote areas with few signs of civilization. The STS also includes several overnight shelters.
