Read more about this location
Neptune Island Waterpark in Hartsville is a larger paid water attraction rather than a simple neighborhood splash pad, but it does officially include the Piratesville Splashpad. The city facility page describes a zero-entry pool, lazy river, wave pool, multiple slides, cabana rentals, party huts, and food trucks. Families looking for a bigger summer outing than a standard spray park may find this the strongest destination option in the Pee Dee region.
