The Great Allegheny Passage (GAP) rail-trail offers 141 miles of hiking and biking between Cumberland, MD, and Homestead, PA, near Pittsburgh. In Cumberland, the GAP joins the C&O Canal Towpath, creating a continuous trail experience, 325 miles long, to Washington, DC. The final mile from Homestead to Pittsburgh is still under construction.
