About
Hamilton Branch State Park occupies a peninsula on 70,000-acre Lake Thurmond, with most of its 150 campsites directly on the waterfront. Six primitive group sites are also offered but 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.)
