Get the Official Guide to Traveling the C&O Canal Towpath and Great Allegheny Passage

Now in its 17th edition, 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 is packed with mile-by-mile trail descriptions, town maps and directories, and itineraries for day trips, weekends, and thru-rides. Included is a removeable, weatherproof, 7.625” x 24.75” map, showing both trails and hundreds of features.

Filled with great photography, an updated list of campgrounds, and suggestions for shuttle services and Amtrak, TrailGuide includes a mileage chart, a plan-your-trip checklist, suggestions on photo ops, and a list of parking and trail access points.  It includes indexes to lodging, restaurants, outfitters, shuttle services, and bike shops.  At 248 pages, it's comprehensive, but still fits nicely into a trunk-mounted rack or in the outside sleeve of a backpack. 

Pick up your copy for just $10 plus postage. Proceeds help fund emergency repairs and enhancements along both trails.
