Scranton, at the center of the Lackawanna River Valley and nestled between the Pocono and Endless Mountains, is surrounded by nature. Just ten miles from the city is Lackawanna State Park, where visitors are welcome to sail or ice skate across the 198-acre Lackawanna Lake. But there's no need to leave the city to enjoy the great outdoors. Nay Aug Park was designed by Frederick Law Olmsted, and includes a zoo, a museum, two Olympic sized swimming pools and a great gorge topped with a treehouse.
