Within Barnwell State Park, this 25-site campground operates year-round under South Carolina Department of Parks, Recreation and Tourism management. The campground arranges sites in a single loop with a centrally located bathhouse providing showers and restrooms that campers consistently describe as clean and well-maintained.
Sites feature electric and water hookups, with full hookup options available at premium locations. The sandy-over-clay ground surface works well for tent camping, though some sites present challenges for larger RVs. Jil S. notes that "Site 16 was awful to get into. Two trees are only about 10 feet apart and once you clear those you have to jackknife." The access road contains potholes that can complicate trailer navigation, particularly for larger rigs.
The park's 25 sites fill regularly on weekends, creating closer quarters than some campers prefer. Trees throughout the campground provide shade and hammock opportunities. Activities center around the lake, which offers a fishing pier, boat rentals including paddleboats and kayaks, and stocked catfish fishing. A tackle loaner program operates for anglers. Hiking trails circle the lake, though some boardwalk sections show wear according to recent visitors.
Park office hours run limited schedules at 11am-noon and 4-5pm daily. Cell service remains spotty throughout the campground, with WiFi available at the office building. For alternative accommodations, Barnyard RV Park provides a different camping experience.
