Pine Creek Gorge, sometimes called The Grand Canyon of Pennsylvania, is a 47-mile (76 km) gorge carved by Pine Creek in Pennsylvania. It sits in about 160,000 acres (650 km²) of the Tioga State Forest and is ~1,280 ft (427 m) from the rim to its deepest point. The brown pathway to the right and parallel to Pine Creek is a Rail Trail. TrailLink information on the Pine Creek Rail Trail.
