South River Falls, Shenandoah National Park.

From the National Park Service: "...at mile 62.8 in the Central District of the park, is truly spectacular. It’s a waterfall of 83 feet, the third tallest in the park. A rock ledge with a stone guard wall offers you a good resting place as you enjoy the sight—and the thundering sound—of falling water. The hike is 2.6 miles roundtrip, with a climb of 850 feet.
