Gambrill State Park: Rock Run Area Campground Professional Guide
Detailed Trail Description from our Guidebook
"Gambrill State Park, at more than 1,100 acres, sits within an area of Frederick County that is packed with parks and recreation opportunities. Gambrill sits on a ridge of Catoctin Mountain and contains the summit of High Knob, modest at 1, 600 feet but providing some impressive views: Frederick City Municipal Forest to the north, Gathland State Park and the Middletown and Monocacy valleys to the south, and the Civil War historical site, South Mountain, to the west.
Gambrill State Park is divided into two recreational areas: Rock Run, at the park entrance, is where you’ll find the campground; High Knob encompasses the top of Catoctin Mountain. Midway between the two areas is the Trailhead Parking Lot, which provides access to Gambrill’s 16 miles of hiking trails."
