150 Miles. No Briefs. No Billables.
Recharge on the Great Allegheny Passage
Exploring the Great Allegheny Passage® is easy to fit into a demanding schedule. With clearly marked access points, trail towns spaced at manageable intervals, and itineraries that range from a single day to a full thru-ride, you can build a trip around your schedule rather than the other way around.
The GAP offers 150 miles of 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 found along 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.
At 232 pages, it’s comprehensive, but still fits nicely into a trunk-mounted rack or in the outside sleeve of a backpack. Included in every TrailGuide is a removable, two-sided, weatherproof map, showing both trails and hundreds of amenities.
