 The park road traverses Catoctin Mountain, and accesses the campground, the trailhead, and the High Knob areas of this park.The park is named after James H. Gambrill, Jr. (1866-1951), a participant in the grain industry and in Frederick city politics, who was a conservationist and frequent visitor to Catoctin Mountain.In an effort to establish a park, Gambrill convinced his fellow businessmen to purchase the land that now makes up the park and donate it to the city of Frederick.
