Caesar Creek State Park is a 3,741-acre park featuring a massive 2,830-acre reservoir created by the U.S. Army Corps of Engineers. The park contains a designated fossil-hunting area where visitors are permitted to keep small quantities of marine fossils. Over 40 miles of hiking trails wind through diverse habitats, including meadows and mature woodlands. The park hosts a pioneer village managed by the Caesar Creek Historical Society, representing life in the 1800s. Boating and fishing are primary recreational activities, with the lake stocked with saugeye, muskie, and bass. Camping options include 287 electric sites and primitive equestrian sites.
