Appalachian Trail: Iron Mountain Gap to Hughes Gap is a 8.1 mile point-to-point trail located near Roan Mountain, TN. The trail is rated as moderate and primarily used for hiking.
I find this to be a great section of trail to hike. Of course I may be a little prejudiced since I've maintained this trail from Greasy Creek Gap to Hughes Gap for 12 years.
Good hike, easy to find great for an afternoon outing.
