About
Barnwell State Park, one of 16 South Carolina state parks built by the Civilian Conservation Corps, centers on three small fishing lakes with a historic CCC spillway. It offers 25 campsites plus 5 cabins (not counted in the total above). Hookup details are not published on the park's own page.
Fees
South Carolina State Parks does not publish a static per-night camping rate on this park's own page - its Itinio reservation system (reserve.southcarolinaparks.com) uses live, date-based dynamic pricing. Check the reservation link for current rates. Pets are allowed on a leash (or other physical restraint) throughout South Carolina State Parks, including campgrounds, per the agency's statewide rules - though pets are not permitted in or around lodging facilities (cabins/villas/lodge rooms). (southcarolinaparks.com/rules-regulations, confirmed live.)
