About the Great Allegheny Passage Conservancy (formerly the Allegheny Trail Alliance)

Founded in 1995, the Allegheny Trail Alliance (ATA) promotes its signature project, the 150-mile Great Allegheny Passage, and coordinates, strengthens, and supports the efforts of allied partners to ensure a high-quality experience for all those enjoy the trail.  In 2021 the ATA changed its name to the Great Allegheny Passage Conservancy and is a nonprofit organization and holds 501(c)3 status with the Internal Revenue Service. 

The Great Allegheny Passage was completed in 2013 after 35 years of trailbuilding between Pittsburgh and Cumberland, Maryland.  In Cumberland, the GAP connects to the 184.5 mile C&O Canal Towpath, and together, they provides a non-motorized, nearly level path between Pittsburgh and Washington, D.C.  The section of the GAP from Cumberland to Ohiopyle is a segment of the Potomac Heritage National Scenic Trail, one of eight nationally designated scenic trails.  The GAP is owned by a mix of public and nonprofit entities, and is maintained exclusively by local residents, the many of them volunteers who live in or near trail towns.
