Noah's Ark Waterpark
This is the undisputed granddaddy of them all. At 70 acres, Noah's Ark is America's largest outdoor water park. The park is known for launching waterslide innovations, like the country’s first looping waterslide, Scorpion’s Tail. Their Black Anaconda watercoaster – a combo waterslide and roller coaster - is a full quarter-mile long.
Kalahari Resort Waterparks
The Kalahari made its mark in the water park world when it debuted its indoor surf ride, the "Flowrider®," which uses 50,000 gallons of water per minute to create a five-foot ocean-like wave. They also introduced the country’s first indoor water roller coaster, the Master Blaster. The Kalahari, with its authentic African theme, is Wisconsin’s largest indoor water park.
Wilderness Hotel & Golf Resort
This is the country's largest indoor/outdoor water park combination, with four indoor and four outdoor water parks that total nearly 500,000 square feet or the equivalent of more than 12 football fields. One of their indoor water parks is under a high-tech dome that allows tropical plants to thrive and people to tan even in the winter.
Chula Vista Resort
There's no such thing as too much water at Chula Vista Resort. Look one direction, and there's the meandering Wisconsin River. Look the other way, and there's an outdoor wave pool with sand beach, a full outdoor water park, and a multi-level indoor water park that houses the country’s fastest indoor water coaster, the Flyan Myan.
Great Wolf Lodge
A multi-story indoor water park complement by an outdoor water park complex easily put this resort in our list of Top Six. Much of Great Wolf Lodge has an "ultimate kids' camp" feel to it with lots of water rides and activities for the younger set. For the more adventurous, the Howlin’ Tornado funnel ride is a must try.
Mt. Olympus Water & Theme Parks
An outdoor surf pool with nine-foot waves and sandy beach…need we say more?! No, but we will. Mt. Olympus has some rad racing slides too - six side-by-side racers that are 350-feet in length. Indoors, the tube slides are towering and the endless river raging.
