Rocks 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 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.
Deer Creek is popular for fishing and tubing. Secluded glens along its shores offer ideal spots for relaxation.
