Twin Falls, also called Rosecrans Falls, is a horsetail waterfall pair in Clinton County, Pennsylvania, with each side about 15 feet high by a lidar survey.
The falls
The World Waterfall Database treats Twin Falls as a side-by-side pair: one drop on McElhattan Creek and one on a tributary entering from the north, each about 15 feet by lidar. Older records put the pair's height at a single figure of 30 feet. Two hiking sites cover the public side at 12 feet and 20 feet instead.
Getting there
The McElhattan Creek side sits on private property and cannot legally be approached from McElhattan Reservoir. The north tributary fall, within Bald Eagle State Forest, has no developed public access at its exact point, but a trail reaches it from the north; hikers must stay on the north side, since the opposite bank is private. That public approach is either an easy 0.7 mile with 36 feet of ascent, open May 1 through October 31, or about 1.1 miles with 105 feet of gain, with the McElhattan Creek fall viewable only from a distance.
When to go
The county-listed trail season runs May 1 through October 31.
On site
The McElhattan Creek fall should only be viewed from the public side; approaching it directly crosses private land. Swimming rules, pets and safety incidents at either fall are not documented.
