Over thousands of years, the Potomac River wound its way through layers of rock. Carving limestone cliffs, roaring falls, and serene winding bends, these waters created a landscape and shaped a nation. Today, the Potomac River corridor is rich in both history and recreation. Offering a chance to both explore your heritage and choose your adventure along the way. The Potomac Heritage National Scenic Trail has something for everyone. History, nature, recreation, wildlife, and conservation are all themes that find a home within the Trail network.
