Located at mile 14.3 on the C&O Canal Towpath in Potomac, Maryland, Great Falls Park is a must-visit highlight for hikers, cyclists, and history buffs alike. A short boardwalk leads to the Olmsted Island overlook, where the Potomac River dramatically crashes over jagged rocks—one of the most scenic views near D.C. For hikers, the popular Billy Goat Trail offers three segments, with Section A featuring challenging rock scrambles and breathtaking river views. The historic Great Falls Tavern, built in 1829, now serves as a visitor center and launch point for seasonal mule-drawn canal boat rides. The towpath itself is flat and easy to navigate, ideal for walking or biking. Amenities include restrooms, picnic spots, and interpretive exhibits. Parking is available at the visitor center (fee required), or you can park for free at nearby Swains Lock and walk or ride 2.5 miles to the falls.
