Escape the Everyday. Blaze Your Trail.
150 miles of spectacular awaits.
The Great Allegheny Passage® offers 150 miles of spectacular biking and hiking from Pittsburgh to Cumberland, Maryland. The nearly-level, crushed limestone path soars over valleys and snakes alongside rivers in Pennsylvania’s Laurel Highlands.
Eastward from Cumberland, the GAP connects to Washington, D.C. by another trail, the C&O Canal Towpath. Our interactive map, TrailGuide, and directory feature trail towns and attractions to be found on both trails.

Official Guide to the Great Allegheny Passage
TrailGuide is packed with mile-by-mile trail descriptions, town maps and directories, and itineraries for day trips, weekends, and thru-rides.
The book also includes a mileage chart, a plan-your-trip checklist, suggestions on photo ops, options for camping, and a list of parking and trail access points.
