Caesar Creek State Park is located in southwestern Ohio, five miles (8 km) east of Waynesville, in Warren, Clinton, and Greene Counties. The park is leased by the State from the U.S. Army Corps of Engineers, who in the 1970s erected a dam on Caesars Creek to impound a 2,830 acre (11 km²) lake. The total park area, including the lake, is 7,941 acres (32 km²). The park has 43 miles (69 km) of hiking trails and 31 miles (50 km) of bridle trails.
