Allegheny Trail Alliance

Founded in 1995, the Allegheny Trail Alliance (ATA) is a coalition of seven trail organizations in southwestern Pennsylvania and western Maryland that is charged with promoting and enhancing the Great Allegheny Passage, a 150-mile multiple use rail-trail system between Cumberland, Md. and Pittsburgh, Pa. and the 52-mile Montour Trail to provide a connection to the Pittsburgh International Airport. Completed in 2013, the GAP connects to the 184.5 mile C&O Canal Towpath in Cumberland and provides a non-motorized, nearly level trail system between Pittsburgh and Washington, D.C. The Great Allegheny Passage section from Cumberland to Ohiopyle is a segment of the Potomac Heritage National Scenic Trail, one of eight nationally designated scenic trails.
