Castle Rock State Park

Castle Rock State Park is located three miles south of Oregon, Illinois on Highway 2. The park is centrally located in the Rock River Hills region of Illinois, and its rolling topography is drained by the Rock River. The park is located along the west bank of the Rock River in Ogle County. The park is very representative of the Rock River Hills area with rock formations, ravines, and unique northern plant associations. A sandstone bluff, adjacent to the river, has given the park its name.
