The Pocono Mountains, commonly referred to as the Poconos, are a geographical, geological, and cultural region in Northeastern Pennsylvania, United States. The Poconos are an upland of the larger Allegheny Plateau. Forming a 2,400-square-mile escarpment overlooking the Delaware River and Delaware Water Gap to the east, the mountains are bordered on the north by Lake Wallenpaupack, on the west by the Wyoming Valley and the Coal Region, and to the south by the Lehigh Valley. The name comes from the Munsee word Pokawachne, which means "Creek Between Two Hills." Much of the Poconos region lies within the Greater New York-Newark, NY-NJ-CT-PA Combined Statistical Area. The wooded hills and valleys have long been a popular recreation area, accessible within a two-hour drive to millions of metropolitan area residents, with many communities having resort hotels with fishing, hunting, skiing, and other sports facilities.
