Bear Run is in the Appalachian Mountains and part of the Pittsburgh metropolitan area. The Fallingwater house, designed by architect Frank Lloyd Wright, is located on this stream at the locality known as Mill Run.
Bear Run is inside the Bear Run Nature Reserve, protected by the Western Pennsylvania Conservancy. Bear Run is a designated Pennsylvania Scenic River. The nearest incorporated town is Ohiopyle, once a resort town for affluent Pittsburghers reaching the Ferncliff peninsula via rail. Ohiopyle today is the focal point of tourism in the Laurel Highlands, drawing many of the same visitors as Fallingwater, located a few miles away on PA State Route 381.
