About the C&O Canal Trail

The C&O Canal Towpath trail runs 185 miles along the Potomac River, from Washington DC to Cumberland Maryland.  These tools will help you plan your next cycling, hiking, running, or canoeing trip along the C&O Canal or the Great Allegheny Passage.

About the Great Allegheny Passage

The Great Allegheny Passage (GAP) trail runs 150 miles through the heart of Pennsylvania, from the Point Park in downtown Pittsburgh to Cumberland Maryland.  There it connects to the 185 mile long C&O Canal Trail. 

Together, the GAP and C&O add up to over 300 miles of blissful trail!  Both trails are included in this website's tools to help you plan your next adventure along the Great Allegheny Passage, the C&O, or both.
