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. Carolina Harbor Water Park
Located within Carowinds, Carolina Harbor is included in your admission to 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 20 watersides, two wave pools, four play areas for little kids and a 1,000-foot-long lazy river that meanders through both South and North Carolina. Oh, and an amusement park with the world's tallest giga coaster is just steps away.
