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.

Trails

Gambrill has over 16 miles of trails for hiking, mountain biking, and horseback riding.

All trails begin at the Trailhead Parking Lot on Gambrill Park Road, between the Rock Run area and the High Knob area.

Many of the trails feature great views. Due to the rocky terrain and steep hills, most of the trails are rated moderate to difficult. However, the White Oak Trail is an easy one-mile loop trail, which makes it a good choice for families with small children.

Pets are allowed on the trails, but must be kept on a leash at all times.

All trails close at sunset.

Horseback Riding

All trails are open to horseback riding with the exception of the White Oak Trail, which is restricted to hiking. Parking for horse trailers is limited. The Maryland Park Service does not rent horses, and only provides the trails as a means of recreation.

Camping

The Rock Run area campground has 13 basic sites, 9 tent only sites, and 8 sites with electrical hookup. Each campsite has a picnic table, fire ring, and latern post. A dump station is available for sewage and potable water. A bathhouse is located at the center of the campground, with hot showers and flush-toilets. Pets are allowed in the campground, but must be kept on a leash and attended at all times.

Camper Cabins

Four camper cabins with electricity are in the Rock Run Campground. Each cabin has a double bed and a set of bunk beds and sleeps 4 people. Camper cabins have a picnic table, fire ring, and lantern post. All cooking must be done outside the cabin. The cabins have no heat. Campers may bring an electric heater or fan. Heat sources should not be left on while the cabin is unattended. No propane heaters are allowed. Campers must provide their own linens. Pets are permitted in Cabin 18.
