Great Allegheny Passage

The Great Allegheny Passage (GAP) is a 150-mile (240 km) rail trail between Pittsburgh, Pennsylvania and Cumberland, Maryland.

Together with the C&O Canal towpath, the GAP is part of a 335 mi (539 km) route between Pittsburgh and Washington, D.C., that is popular with through hikers and cyclists.

[4] The GAP was completed in 2013 when the section between West Homestead and Point State Park in Pittsburgh opened.

Great Allegheny Passage was selected in 2001 by the ATA after six years and more than 100 proposals as a name evocative of the geography and historical heritage of the trail.

The GAP also includes the Mountour Trail, a 52-mile (84 km) branch that serves Pittsburgh International Airport.
