Great Falls National Historical Park protects the dramatic series of waterfalls and the historic Patowmack Canal along the Potomac River, offering visitors a unique blend of natural beauty, outdoor recreation, and early American engineering history.
Great Falls National Historical Park spans both Maryland and Virginia along the Potomac River, showcasing one of the most spectacular natural features of the Mid-Atlantic region. The park preserves a stretch of the Potomac River where water cascades over a rugged series of falls and rocky gorges that drop nearly 76 feet over less than a mile. This natural spectacle is paired with remnants of the Patowmack Canal, a pioneering early 19th-century transportation project designed by George Washington to improve navigation around the falls. The park’s geography is defined by steep cliffs, dense hardwood forests, and the river’s powerful flow, providing habitat for various wildlife including deer, osprey, and migrating fish. Visitors can explore several overlooks offering panoramic views of Great Falls, hike along well-maintained trails, and paddle in calm river sections below the rapids. The park’s historical angle is significant as it preserves early American efforts at canal building and river commerce. The Patowmack Canal was the first canal in the United States constructed to bypass river obstacles and facilitate westward expansion. Today, Great Falls National Historical Park is a popular destination for hikers, kayakers, anglers, photographers, and history enthusiasts. Its proximity to the Washington, D.C. metropolitan area makes it easily accessible for day trips. The park combines dynamic river scenery with interpretive exhibits and educational programs that highlight both natural and cultural heritage.
