TrailGuide is the official, authorized guidebook for the Great Allegheny Passage and C&O Canal Towpath, covering two scenic trails — and one amazing journey. TrailGuide is packed with trail descriptions, town maps, business listings and services for tourists. Included is a two-sided, weatherproof 16″ x 24 1/2″ map, showing both trails and hundreds of features. Mileage charts, elevations tables are also provided, as well planning checklists, mile-by-mile highlights for all 333 miles between Washington, D.C. and Pittsburgh. This year’s book has lots of great content, including suggestions for side trips, a camping chart, and new pictures. Proceeds from the book are reinvested into trail improvement projects.
