What’s the GAP?

Connecting Pittsburgh in Pennsylvania to Cumberland in Maryland, the Great Allegheny Passage stretches for nearly 150 miles through the Appalachian Mountains. It traverses rugged natural terrain and is dotted with small towns, offering plenty of opportunities for cyclists to rest along the way. We offer four, five and six-day self-guided bike tours.

Riding the Great Allegheny Passage

With most of the trail converted from abandoned rail beds, the surface is ideal for hybrid and/or touring bicycles, with an average grade of less than 1%. At the highest point of the trail, you’ll cross the Eastern Continental Divide, after which the trail drops around 1,750 feet over 20 miles before reaching Cumberland.

Trail Highlights

The Great Allegheny Passage incorporates defunct corridors of the Baltimore and Ohio Railroad, the Pittsburgh and Lake Erie Railroad, and the Western Maryland Railway. Highlights along the route include Ohiopyle State Park and “Fallingwater” designed by Frank Lloyd Wright, as well as one of only two surviving cast-iron truss bridges in North America.
