Tuscarora Trail: Cowans Gap Lake To Buchanan Trail is a 17.4 mile lightly trafficked out and back trail located near Fort Loudon, Pennsylvania and is rated as difficult. The trail is primarily used for hiking, trail running, and backpacking and is best used from April until October.
I think this should be called the Tuscarora Trail which is a spur trail to the Appalachian Trail. Two miles of it goes through Cowans Gap State Park. From the main parking lot you can take the trail south to a beautiful overlook of Path Valley and Franklin County (about 9 miles out and back). Or you can take the trail south until Geyer trail to Cameron trail then to Plessinger Trail which will get you back to your car (about 5 miles). There are two pretty steeps areas on both these paths and the trail is rocky at times.
We only hiked 6 mikes of this link trail but the back half was straight up a mountain side with a 40 pound backpack in the rain. Other than that the mountain side scenery overlooking the park was amazing.
