The C&O Canal Towpath Trail and Great Allegheny Passage

C&O Canal Trail on the Great American Rail-Trail

The C&O Canal and GAP are part of the Great American Rail-Trail, a 3700-mile bike route across the United States, from Washington DC to Seattle. This coast-to-coast route uses rail-trails and greenways for a car-free path across the country.
Although this ambitious project will take years to complete, over half of the Great American Rail-Trail already exists. The C&O makes up the Maryland portion of the route, and most of the Pennsylvania portion is comprised of the Great Allegheny Passage.
This map, from the Rails-to-Trail Conservancy, shows the route. Green and green-yellow sections are already developed, red sections still need to be developed, and the white boxes are not yet determined.
