At the base of Dark Hollow Falls - About 75 feet high, I'd guess. One thing that I know is that it's 1.6 miles down the hill from the parking area (and not the 0.6 miles, as in my wife - "Oh go ahead down; it's only six-tenths of a mile). Yeah, right! The falls were spectacular after 3-4" of rain the day before compliments of hurricane Jeanne leftovers. My weekly trip to Shenandoah National Park.
