The West Rim Trail is a 30.5 mi (49.1 km) linear hiking trail in Lycoming and Tioga Counties in north central Pennsylvania. The trail mostly follows the edge of Pine Creek Gorge, also known as the Grand Canyon of Pennsylvania, which is up to 1,000 feet (300 m) deep and about 2,000 feet (610 m) wide from rim to rim in the area traversed by the trail. The trail is entirely within Tioga State Forest and is known for its large number of vistas overlooking the gorge, which is a National Natural Landmark and one of the deepest gorges in the eastern United States.
