Guests getting splashed by Tidal Wave.

Tidal Wave

A Tidal Wave of Fun.

Pile into the large 20-person boat and try to catch your breath while we crank you up notch by notch, higher than the trees. Brace yourself for what’s comes next — an ultra-steep drop down a 50-foot waterfall, straight into the 300,000 gallon lagoon below.

Don’t get too comfortable on the brief river flume, because any second now you’ll be plunging headfirst all the way down into that huge pool. The massive splash roars over your boat in a tower of water that's 20 feet high and 80 feet wide.

You better believe the water’s so high it will drench you and everything in sight, including the spectators watching from the pedestrian bridge.
