Big Kahuna

Don’t Let the Big Kahuna Boss You Around!

Get the real feel of racing down mountain rapids, without the hassle of having to climb a mountain first. Piling your whole family or a gang of friends onto one of this slide’s jumbo-sized rafts will be easy. However, navigating the ultra-wide, steep, slick, and snaking route as a team may be more challenging. Someone’s gotta be the Big Kahuna and call all the shots!

This bright red, massive open-air slide will carry your entire crew down a six story tall river of white foam and crazy good times.

Your crew is in for a never-ending blast of pure whitewater rafting bliss. A little bit of teamwork will help you guide the raft down the twisty turns of this sloshy wet river run with very steep walls. The high canyon walls mean you’ll all be banking up every curve. You can just let the current take you where it will—backwards, forwards—any direction works as long as it’s wet.

Your entire entourage will be plummeting down ridiculously steep slopes together on a splashy race for the pool. You’re all big shots now.
