Harrison Lake State Park is a 142-acre woodland facility situated in Fulton County, Ohio, featuring a 105-acre man-made lake. The park offers 140 campsites, including both electric and non-electric options, equipped with showers and flush toilets. Recreational activities center on the lake, which permits boating with electric motors and non-motorized vessels. Anglers frequent the water for its populations of largemouth bass, bluegill, and channel catfish. The park grounds provide a network of hiking trails that traverse oak-hickory forests and grassy meadows. A designated swimming beach is maintained for public use during the warmer months. Picnic shelters, playgrounds, and horseshoe pits are available for day-use visitors. The site remains a regional destination for wildlife observation due to its diverse forest and aquatic habitats.
