Neptune Island Waterpark

Neptune Island Waterpark is a family-oriented outdoor water park in Hartsville, South Carolina, where a quarter-mile lazy river, a wave pool, a 30 mph body slide and a pirate-themed splash pad turn a summer afternoon into a full day of water play. Opened in 2018 and run by the City of Hartsville, the park is built for all ages, from toddlers in the shallow splash zone to thrill-seekers chasing the fastest slide. The mix of mild and wild attractions makes it easy to settle into your own pace: race your friends down the mat slides, float the lazy river on a tube, or claim a shaded cabana overlooking the waves. Parking is free, lifeguards are on duty at every attraction, and a relaxed, family-friendly atmosphere runs through the whole island.
