Great Falls Park has fifteen miles of hiking trails, some of which are multi-use for biking and horseback riding. Below are descriptions of the trails. If you would like assistance in planning a hike, contact us or stop by the visitor center desk. Take note that there are two (2) national parks in the area of Great Falls - Great Falls Park on the Virginia Side (this website), and the Chesapeake and Ohio Canal National Historic Park on the Maryland side. If you are looking for the Billy Goat Trail, it is located on the Maryland side. The River Trail is similar, treks along the Potomac River in the scenic Mather Gorge and is located on the Virginia side.

North River Trail to Riverbend County Park

Length: 1.5 miles, one-way, between the Great Falls visitor center and the Riverbend Park visitor center.
Difficulty: Easy, with one moderate section at the Aqueduct Dam
Use: Hiking only. No horses or bicycles. The section that passes over the Aqueduct Dam is not wheelchair or stroller accessible.

This trail runs next to the Potomac River. It is an excellent place for wildflowers in the spring and bird-watching throughout the entire year. Watch for signs of beaver activity as you hike. The occasional bald eagle, along with herons, ducks, and other water birds are easily observed from the trail. Fishing spots are abundant here and are easy to access from the trail. A Maryland or Virginia state fishing license is required for ages 16 and up.

Most of the trail is straight and level, with the exception of a steep, rocky hill that must be climbed to bypass the Aqueduct Dam. This trail will flood when the Potomac river levels rise, and trail conditions after a period of high water will be very muddy.

Swimming and wading are prohibited in both Great Falls and Riverbend Park. Dogs must be on a leash at all times in both parks. Use care while hiking near the Aqueduct Dam and do not attempt to walk out onto the dam itself. Low-head dams like this one have a powerful hydraulic on the downstream side. Getting caught in one of those hydraulics is usually fatal.

This trail connects to the Gabrielson Trail. It is possible to hike to Algonkian Regional Park in Loudoun County, a one-way distance of approximately 12 miles.
