Great Allegheny Passage
Follow a former rail corridor from Pittsburgh toward the mountains and Maryland.

Artwork inspired by John Kane
The Great Allegheny Passage links Pittsburgh with Cumberland, Maryland, over roughly 150 miles of mostly gentle rail grade. Its river bridges, old tunnels, and changing industrial landscapes make it more than a distance challenge. The Pittsburgh western terminus gives an easy taste; farther east, the route becomes a multi-day trip through the Youghiogheny valley and Laurel Highlands.
For a first ride, choose a short out-and-back and check surface and tunnel conditions. The trail is largely crushed limestone rather than continuous pavement, and lodging or shuttles must be planned for a through trip. The map opens the Pittsburgh terminus, not a midpoint or every trailhead; the official trailhead guide is essential for a longer itinerary.
