Rocks State Park

Rocks_FallColors.JPGRocks State Park features 855 acres of rocky forest land nestled in rural northern Harford County. Primary attractions at Rocks include the King and Queen Seat and Kilgore Falls. The main section of the park includes three picnic areas, 3.5-miles of hiking trails, and access to Deer Creek, which is ideal for fishing, wading and tubing. The park’s two satellite properties, Falling Branch (home to Kilgore Falls) and Hidden Valley, are a short drive from the main park.

Rocks was one of the first state parks in Maryland created for the expressed purpose of protecting a unique natural feature. In 1949, the State of Maryland purchased the park to preserve the King and Queen Seat, a spectacular 190-foot high rock outcrop overlooking Deer Creek.

Rocks State Park is known to fill to capacity on summer weekends and holidays. Parking is only permitted in parking lots and authorized pull-offs. Visitors will be turned away if parking lots fill to capacity. Please plan to arrive early.

King and Queen Seat

The King and Queen Seat rises 190 feet above Deer Creek. The soaring natural rock outcrop provides a breathtaking view, as well as a challenge to the skilled climber. There are many vertical rock faces on the outcrop, some of which are as high as 94 feet. Please use caution in this area.

The King and Queen Seat can be reached from the Rock Ridge Picnic Area, the park’s main office via the White Trail, or from Rapids parking via the Purple Trail. Novice climbers are encouraged to seek professional training before attempting to climb the King and Queen Seat. Climbs range from 8 to 115 feet, and are suitable for skill levels 4 to 5.12.

According to legend, the King and Queen Seat was a ceremonial gathering place for Susquehannock Indians. While no evidence supporting the legend has ever been found, the “Rocks of Deer Creek” nevertheless attracted trainloads of tourists in the late 1800's.

Trails and Hiking

Hikers and pets on a leash are welcome on the park’s 3.5 miles of trails. Trails in the main part of the park connect various points of interest and the picnic areas. Most of the park’s trails are steep and rocky, so please plan ahead and wear appropriate footwear. Parking is only permitted in parking lots and authorized pull-offs.

Trails in the main part of the park are best suited for hiking. Rocks State Park does not offer equestrian riding trails. Horseback riders are encouraged to visit Susquehanna State Park or the Sweet Air Area of Gunpowder Falls State Park.

Deer Creek Recreation

Deer Creek, a designated State of Maryland Scenic River, meanders across Harford County before joining the Susquehanna River below the Conowingo Dam. On its journey, it cuts through the center of the main portion of Rocks State Park. All those seeking to recreate on the creek are encouraged to scout out the area ahead of time.

Everyone is welcome to wade, swim in and tube on Deer Creek at their own risk. There are no lifeguards. Wading, swimming and tubing in the Deer Creek Rapids is strictly prohibited.

Deer Creek is best suited for canoeing and kayaking in the spring. Water levels vary throughout the rest of the year. The U.S. Geological Survey gauge along Rocks Road (Maryland Route 24) at the lower end of Rocks State Park should read at least 2.5 feet for optimal canoeing/kayaking. Only expert paddlers should attempt to travel through the Deer Creek Rapids.

Fishing on Deer Creek

Trout are stocked in the spring and fall on this scenic creek that meanders through woodland, hills, valleys and farmland. Look to the Maryland Freshwater Fishing guide for more information on regulations. A Maryland Non-Tidal Fishing License and a trout stamp are required for anyone 16 years-of-age or older. For licensing information, please visit: compass.dnr.maryland.gov/dnrcompassportal. Deer Creek closes to fishing for a few weeks every spring.
