Get ready to kick off summer at Raging Rivers Waterpark. The park officially opens May 23 for its 37th season, bringing back all the fan-favorite attractions and plenty of ways to cool off.

Take on the Breaker Beach Wave Pool, race down the Cascade Body Flumes, or float your way through the Endless River. Younger guests can explore Itty Bitty Surf City and Treehouse Harbor, while thrill-seekers won’t want to miss the Shark Slide, Runaway Rafts, the Swirlpool, and the iconic Mississippi Monster.

Start your Memorial Day Weekend the right way, by diving into a full day of sun, slides, and nonstop summer fun.
