Aggresive, narrow, very rugged singel-track. This is the Barbours Creek Wilderness Area that allows hunting. If you ride during hunting season I recommend checking in with the Ranger's office and ware a bright orange vest.
About ten miles west of Roanoke on Route 311, you can access this trail in the New Castle Ranger District of the Jefferson National Forest.
