There is nothing as refreshing or enlivening as a dip in the icy-cold waters of a mountain stream. The “Y,” near the Townsend entrance to the park, is probably the most popular swimming hole in the park. Other good places to swim are at the Abrams Creek campground, the Greenbrier picnic area, and at Cosby.
Because swimming in rocky, fast-moving rivers can be dangerous, the park service officials frown on swimming. Despite this, many people do it. If you swim, remember that there are no lifeguards in the park, and that hidden rocks and ledges lurk beneath the surface of the water. Never dive into streams or rivers.
