The Potomac River Basin is a massive network of more than one hundred rivers draining over nearly 15,000 square miles of land and provides about one-fifth of Chesapeake Bay’s water. This trail tours some of the creeks of the Potomac River Basin, mostly along paved bike paths through residential areas and forested parks with some short sections on connecting roads. You will parallel the Northeast and Northwest Branches of the river as well as Sligo Creek. The paths are all paved and the terrain is mainly flat with a gentle and gradual descent to the end at Forest Glen Station.
