Great regional park, hailed as Northern Virginia's backyard and very popular for picnics and barbecues. Common activities include hiking, rock climbing, and whitewater rafting. There can be lines into the park on weekends, especially on holidays like Fathers' Day and Labor Day, so plan ahead. The park has several marked trails, including the very popular Billy Goat Trail.
Great Falls Park is a small National Park Service (NPS) site in Virginia, United States. Situated on 800 acres (3.2 km2) along the banks of the Potomac River in northern Fairfax County, the park is a disconnected but integral part of the George Washington Memorial Parkway. The Great Falls of the Potomac River are near the northern boundary of the park, as are the remains of the Patowmack Canal, the first canal in the United States that used locks to raise and lower boats.

Far less crowded than Great Falls Park. Walk for miles in the undeveloped forested hills along the Potomac. Not to be confused with the Maryland parks Little Seneca or Seneca Creek.
