The St. Louis area waterpark opens for the 2021 season this Saturday, May 29, with more places for families to kick back and relax, more food options, and more entertainment.

“Raging Rivers is the hottest place to cool off this summer, and there is more to enjoy this season,” said General Manager Ken Handler. “After making many park updates, families can relax in 30 new cabanas, dine on our updated menu and come face to face with sea lions visiting in June. We can’t wait to welcome everyone back this summer.”

As part of the park’s multi-million dollar purchase and expansion earlier this year, the park will open its doors for the 2021 season with more than 30 cabanas and updated food menus across the park. In addition to these park updates, guests can experience new, live entertainment with Sea Lion Splash, an educational and entertaining show running for a limited time, Saturday, June 19 to Sunday, June 27.

Operated by Squalus, Inc., Sea Lion Splash is the only traveling sea lion show in the United States. The whiskered wonders come alive on stage with singing and dancing, acrobatics, and silly antics to please the crowd. Not only will the sea lions dazzle, but they will also teach guests about the plight of sea lions and what humans can do to help. The show is included with park admission or a Season Pass, and VIP Sea Lion Packages are available for an additional fee.
