This is Blue Hole Falls in Carter County. Many just call it Blue Hole. I think you can see why.
DIRECTIONS: Starting at the junction of state road 91 and U.S. 321 in Elizabethton, drive east on 91 for 10 miles. Turn left (north) on Panhandle Road at the national forest sign for blue hole. Drive 0.9 miles to the parking area. The trail to the right leads 0.1 miles down wooden steps to the base of the main falls.
