Hiking Bill's post on the tower here.
Directions: From Elizabethton, TN take Route 91 (Stoney Creek) east for 10 miles, turn left on Panhandle Road and reset your odometer. At 1 mile you'll pass by the parking area for the Blue Hole on your left. At 1.4 miles you'll come to a gate that is typically closed in the winter months. (I'm told there's a trail leading from here to the top, but have not investigated that for myself. If there is, it's probably a steep, four mile trail from this point to the fire tower.) At 4.4 miles, the road splits. To your right is the gated road leading to the tower -- park here. The tower is one mile further up the road on foot - it's a fairly easy grade to the top.
