Rocks has 855 acres of dense forests and massive boulders riding above Deer Creek. The King and Queen Seat, once a ceremonial gathering place of the Susquehannock Nation of Native Americans, is a natural 190 foot rock outcrop. This cliff, reached by scenic trails, affords a view of the rolling hills and farmland of Harford County. Also preserved on park property are many structural remains from the days when the Maryland and Pennsylvania Railroad wound its way through Rocks, helping the farms and quarries of Northern Harford County to prosper. See the park map for more information. Deer Creek is popular for fishing and tubing. Secluded glens along its shores offer ideal spots for hiking and relaxation. The facility features opportunities for fishing, hiking, picnicking, canoeing and tubing, as well as bow hunting, rock climbing and repelling. Playgrounds, shelters, and comfort stations are available at each of the three picnic areas. Summer campfire programs are held every Friday night at 7 p.m., from Memorial Day to Labor Day, at the Rock Ridge Amphitheater. Pets are not permitted in any of the picnic areas. Pets are permitted on the trails but must be on leashes at all times. Please visit the website for fees, maps and additional information.
