TrailGuide is the official, authorized guidebook for traveling the Great Allegheny Passage and C&O Canal Towpath, covering two scenic trails -- and one amazing journey between Pittsburgh and Washington, D.C. It's packed with mile-by-mile trail descriptions, town maps and directories, and itineraries for day trips, weekends, and thru-rides. Included is a two-sided, weatherproof 7.625” x 24.75” map, showing both trails and hundreds of features. TrailGuide 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.
