Wisconsin Dells found its place in history as the Waterpark Capital of the World. Among the best parks are Noahs Ark Waterpark (the largest outdoor park with the most diverse set of slides), Kalahari Resort (a gigantic indoor waterpark, perfect for any season), Mt. Olympus Water & Theme Park (a nice balance of slides and rides), Wilderness Resort (several indoor and outdoor parks), and Chula Vista Resort (well, known for its family, friendly attractions).
