The Pocono Mountains, commonly referred to as the Poconos, are a geographical, geological, and cultural region in Northeastern Pennsylvania. They overlook the Delaware River and Delaware Water Gap to the east, Lake Wallenpaupack to the north, the Wyoming Valley and the Coal Region to the west and the Lehigh Valley to the south. The name Pocono is derived from the Munsee word Pokawachne, which means "Creek Between Two Hills".
