Wolf Ridge Trail is a 14.3 mile out and back trail located near Franklin, TN that offers scenic views. The trail is rated as difficult and primarily used for hiking and camping.
Directions from Fontana Lake, NC: Take SR 28 west to the Twentymile Ranger Station. Begin on Twenty Mile Creek Trail from behind ranger station. When this trail forks, bear left to reach Wolf Ridge Trail.
This trail is often used to loop around Gregory's Bald. Its hard to imagine it being used as an out and back trail. Its end destination at Parsons Bald is diminished by the fact that the "bald," itself, is practically reforested, and the nearby and far more spectacular GB is only a mile further down the GB Ridge Trail. More details on the WRT are in my review of the Gregory Bald via Twentymile Trail.
