Gambrill State Park is a beautiful mountain park, located on the ridge of the Catoctin Mountains in Frederick County. Its most popular feature is the 16 miles of trails for hiking, mountain biking and horseback riding. The park is separated into two areas, the Rock Run area and the High Knob area. From the 1600-foot High Knob, three stone overlooks offer breathtaking views of the Frederick and Middletown Valleys, then continue to the northern reaches of the Shenandoah Mountains. The High Knob area also offers wooded picnic areas, three picnic shelters and a large stone lodge, called the Tea Room. The picnic shelters and the Tea Room are available for reservation. The Rock Run area offers a cozy family-style campground, a picnic area and a small pond for fishing. Gambrill State Park offers an accessible comfort station and campground building.

The park has two visitor sections: Rock Run has a campground, picnic tables, camping and a small fishing pond; High Knob has extensive picnic facilities and stunning views to the east and west.

The Trailhead Parking Area off Gambrill Park Road between the Rock Run and High Knob areas is a convenient access point for a network of over 16 miles of trails. Gambrill State Park is part of a large area of contiguous woodland that includes the Frederick City Watershed and Cooperative Wildlife Management Area, Cunningham State Park, and Catoctin Mountain Park.

Early morning at the Rock Run area provides the most rewarding birding. A walk along the Rock Run camping area rim road is always productive. Please respect camper privacy and avoid walking  through camp sites.
