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.
