Year Round Water Park Fun in Illinois

Where to Find Find Indoor Water Parks

Pirates Cay Water Park Illinois
Orange Lake Country Club

The indoor water park phenomenon started in Wisconsin Dells in 1994 and spread throughout the Midwest, including Illinois (and eventually across the US and beyond, soon thereafter). It only makes sense. Why should we be restricted to riding water slides and enjoying wave pools during summer's short window? And if it is overcast or rainy? No problem! The weatherproof parks are always a balmy 78 degrees or so and are protected from the elements.
