Located at the YMCA, the Orangeburg County Aquatic Park offers visitors of all ages the chance to splash, slide and float. The park has two big twisty slides, an awesomely terrifying bowl slide, a lazy river, and a watery playground with slides, ramps, climbing ropes and a big bucket that fills with water and occasionally dumps it all over the unsuspecting kids below, setting off a round of squealing and laughing. There's a snack bar and plenty of lounge chairs, too.

3. Boomerang Bay Waterpark
Located within Carowinds Amusement Park, Boomerang Bay Waterpark is included in your admission to Carowinds, the sprawling amusement park that straddles the South Carolina/North Carolina state line. It's certainly the biggest of all the inland water parks. There are more than a dozen watersides, five pools (including two wave pools), two special areas for little kids, a 1,000-foot-long lazy river that meanders through both South and North Carolina, and a three-story water playground. Oh, and an amusement park with the world's tallest giga coaster just steps away.
