This park along the Potomac Valley covers about 630 acres and is known for its forests, wetlands, streams, and rock outcrops. Visitors can see views of the Potomac River and the C&O Canal. Its trails, named for the Civil War complex they were part of, were once used to move supplies. The park is open for hiking, biking on one designated route, and horseback riding on some trails. It has no restrooms, and parking is limited to two gravel lots along River Road.
