About
Starting in Cumberland, Maryland and ending in Downtown Pittsburgh, the Great Allegheny Passage is a spectacular 150-mile nonmotorized path that soars over valleys, snakes around mountains, and skirts alongside the Casselman River, Youghiogheny River, and Monongahela River on a nearly-level, crushed-limestone surface. Tracing old footpaths and railroad corridors through the wilderness, it offers glimpses into the country’s westward expansion and industrial might. When paired with the connecting CandO Canal Towpath, it makes long-distance trail travel possible between Pittsburgh and Washington, D.C.
