The ¾-mile boardwalk traverses Neabsco Creek, allowing hikers access to wetlands where the tall grasses and marsh filter pollution from the river and provide a rich habitat for great blue herons, wood ducks, mallards, sparrow and red-winged blackbirds, just to name a few of the winged wildlife known to populate the area. The walkway is part of the Potomac Heritage National Scenic Trail, which was established by Congress in 1983 designating an 800-mile trail network stretching from the Allegheny Mountains in Pennsylvania to the Potomac River, winding through Pennsylvania, Maryland, Washington, D.C. and Virginia.
