Maryland’s most-visited National Park, the C&O Canal National Historical Park, features a Visitor’s Museum at Canal Place with a life-size replica of a canal boat and extensive interpretive exhibits on the canal’s construction, locks, aqueducts, mules, and crews. The park is home to the connection between the two internationally-recognized bike trails; the C&O Canal Towpath and the Great Allegheny Passage, part of a system of bike trails that stretch 333 miles from Washington, DC, to Pittsburgh, Pennsylvania.
