Splash on the Wild Open River!

Gear up for the ultimate river rafting experience. Get ready for the rush of your life as you thunder down seven acres of the wildest white-water rapids in the Midwest.

You’ll strap into your full-scale round river raft and set loose into the raging downstream flow, where wildly unpredictable currents will toss you around without warning, and treacherous falls will send you shooting over the edge.

Very tall cliffs and a woodsy forest of trees surround you on this totally immersive ride. You are swung wildly around rocks, into swirling whirlpools, and narrowly avoiding raging waterfalls, blasted with water from all directions. As you rush down steep rocky channels, banging into the stone walls, white water waves come crashing over the raft.

You will definitely get splashed, and if you are unlucky—or lucky, depending on how hot it is that day—you might even get completely drenched. With a little luck the current will spin you around in the nick of time, right before you hit that next patch of rapids.

Will you get dunked? Just hang on tight and don’t plan on staying dry!
