Located in the Adirondacks' Grass River Wild Forest, Harper Falls can be found on the North Branch of the Grass River.
An easy hike brings visitors 0.6 miles to the falls, and there is a campsite at the trail's end.
Park on Donnerville Road (a seasonal, gravel road), just overa half mile from CR 27. Follow the Harper Falls Trail from the parking area, and you should begin to hear the falls after 0.5 miles.
The campsite is marked by a yellow DEC disc.
