The Chesapeake and Ohio Canal, abbreviated as the C & O Canal, operated from 1831 until 1924 and runs parallel to the Potomac River from Washington D.C. to Cumberland. The total length of the canal is about 184 miles and has an elevation change of 605 feet that is accommodated by 74 canal locks. There were over 150 culverts and 11 aqueducts for the crossing of streams. The canal way is now maintained as a park that is overflowing with history. The trail is wide, flat, and made up of hard-packed dirt. Along with stunning river, forest, and mountain views throughout, this section of the towpath passes through Great Falls Park with a majestic waterfall. There are many parking areas, usually every few miles, allowing you to shorten or lengthen your ride.
