Rocks State Park

The first land purchases for what is now Rocks State Park began in 1951. Originally slated to be Deer Creek State Park, these were the first land purchases made by the State of Maryland for the express purpose of creating a park.

King and Queen Seat at Rocks State Park

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. 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.
