The Potomac Heritage Trail, also known as the Potomac Heritage National Scenic Trail or the PHT, is a designated National Scenic Trail corridor spanning parts of the mid-Atlantic region of the United States that will connect various trails and historic sites in Virginia, Maryland, Pennsylvania, and the District of Columbia. The trail network includes 710 miles (1,140 km) of existing and planned sections,[1] tracing the natural, historical, and cultural features of the Potomac River corridor, the upper Ohio River watershed in Pennsylvania and western Maryland, and a portion of the Rappahannock River watershed in Virginia. The trail is managed by the National Park Service and is one of three National Trails that are official NPS units.[2]
Unlike many long-distance hiking trails such as the Appalachian Trail, the Potomac Heritage Trail is an informal route with numerous side trails and alternatives, some in parallel on each side of the river. Currently, many of these are separate, connected to the others only by roads.[3][4] The PHT crosses the Appalachian Trail near Harpers Ferry, West Virginia, and is concurrent with the American Discovery Trail along the portion of the C&O Canal Towpath between Oldtown, Maryland, and Washington, D.C.[3]
