The historic Camp Hook area at Twin Creek offers three frontcountry campsites with access to the park's extensive hiking trail system. The more than 10 miles of trails in the park's rugged terrain connect to the 22-mile Twin Valley Trail and take you along the beautiful Twin Creek, by a prehistoric Indian mound and up to a hilltop vista. The amphitheater in the former Boy Scout camp makes this a great place for large groups to hold ceremonies. Permit required. The amphitheater is permitted separately on a first-come, first-served basis.
