Whiskey Springs is a well known rock climbing area on the Appalachian Trail. The boulders range in size and skill level. Safety equipment is needed. To approach, park in the small pull off and walk up the right side of the road and enter the woods at the white AT blazes (look for the small footbridge in the last photo). Follow the trail steeply up the ridge until you reach the first outcrops, about 1/4 mile. The largest rocks are located approximately .6 miles from the road entrance.
The pull off is located at 40.009732, 77.12833.
