Rocks State Park

Rocks State Park is located in the Deer Creek watershed near Pylesville in Harford County. It is managed by the Maryland Department of Natural Resources. The park consists of four non-contiguous areas totaling 1,060 acres. The main area, 855 acres in size, consists primarily of dense forest characteristic of the Piedmont. Its most notable feature is a 190-foot rock outcrop, known as the King and Queen Seat, which overlooks Deer Creek to the east. In fact, the park was created to protect this spectacular natural resource. A visit to Rocks State Park presents the opportunity for a quiet ramble through the forested slopes.

The Falling Branch area of Rocks State Park is located about five miles north of the main park on a separate 67-acre parcel of land. It is home to the 17-foot high Kilgore Falls, which is Maryland’s second highest vertical drop waterfall.

Just southwest of the Falling Branch area is the Cameron Hunting Area of Rocks State Park, a 77-acre forested tract along Falling Branch which is a tributary of Deer Creek. The Cameron area has a small parking area on the north side of Falling Branch Road, with a short foot-trail heading north. There are no marked trails here, and the area is seldom birded.

The Hidden Valley tract of Rocks State Park is located five miles northwest of the main part of Rocks State Park at the intersection of Madonna, Telegraph, and Carea Roads. This undeveloped area offers a beautiful hiking trail and fishing spot along Deer Creek. Parking is available for 8 to 10 cars. Parking along roadways is not permitted. There are no picnic tables, grills or restroom facilities.

The main part of the park has over 3.5 miles of trails that connect various points of interest and three picnic areas. Most trails are steep and rocky, so plan ahead and wear appropriate footwear. Parking is only permitted in parking lots and authorized pull-offs.

The King and Queen Seat provides an excellent vantage point for hawk watching. The face of the outcrop is popular with skilled rock climbers, but is considered too difficult for novices. 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 the Rapids parking area on MD Route 24 (see Directions below) via the Purple Trail. See trail map at link at left.

Rocks State Park features three developed picnic areas in the main tract: Hills Grove, Wilson’s and Rock Ridge. These areas include tables, grills, restroom facilities, and playground equipment. The Hills Grove and Wilson’s Areas are wheelchair accessible. Pets on a leash are permitted in any of the picnic areas, as in the rest of the park. There is also a children’s nature exploration area featuring miniature rock-climbing opportunities.

Fishing, canoeing, kayaking, tubing, and wading are all available in Deer Creek, but the Deer Creek Rapids should only be attempted by expert paddlers.

The park offers interpretive programs throughout the summer, and upon request (pending staff availability). Interpretive activities include nature and history hikes, talks, crafts and demonstrations for children, adults and school groups. Fees may apply. For the current schedule, check
