Rocks State Park

King and Queen seat

Rocks State Park has 855 acres of dense forests and massive boulders rising above Deer Creek. The King and Queen Seat, once a ceremonial gathering place of the Susquehannock Indians, 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 of the Maryland & Pennsylvania Railroad, which once helped 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 relaxation.
