Catoctin Mountain Park, located in north-central Maryland, is part of the forested Catoctin Mountain ridge that forms the eastern rampart of the Appalachian Mountains. Approximately 8 square miles in area, the park features sparkling streams and panoramic vistas of the Monocacy Valley. Catoctin Mountain Park is managed by the National Park Service and lies north of, and directly adjacent to, the similarly-sized Cunningham Falls State Park.
