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 consists of fast moving flat water some riffles produced by low ledges and it makes several turns winding through beautiful foothills. The valley is very scarcely inhabited and presents a rather wild riverscape with a well-traveled railroad line running parallel. The water is clean and clear and fishing is usually rewarding. Though this trip can easily be made in a day, stopping to camp at the Sorrel Ridge Canal Campsite makes a wonderful two-day trip.
