The Potomac is the longest and most diverse river system in Maryland, reaching from the cold, high plateau of the Alleghenys to the broad waters of the Chesapeake Bay and tidewater. This section follows a relatively straight, eastward course as it cuts through the lovely, low hills and ridges where you will enjoy the impression of remoteness. The water is mostly flat, broken by a few riffles formed by tiers of low ledges. Two clear and clean side streams, Town Creek and Little Cacapon, are excellent detours to explore and find great swimming holes.
