Noah's Ark Water Park
Water Park · Wisconsin Dells, Wisconsin
Seventy acres of outdoor waterpark on the Wisconsin Dells Parkway, opened in 1979 and now generally accepted as the largest outdoor waterpark in the United States — around fifty rides and attractions, three miles of slides, two wave pools and two lazy rivers holding roughly five million gallons. It was bought by Herschend in early 2025. Several of its slides were genuine firsts: Scorpion's Tail was the first upside-down looping body slide in the country, dropping riders through a trap door into an inverted loop.
