Find Illinois Indoor Water Parks

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. There is a hotel with an indoor water park (and one one the way) as well as some standalone parks around the state, which follow.

During a building boom in the mid-2000s, many indoor water park resorts were proposed for Illinois. But the recession that started in 2008 ended many of the plans, including Frontier Lodge in LaSalle, Grizzly Falls Resort in Rosemont, Sun Island Water Park Resort in Hoffman Estates, and Waves of Fun, an indoor water park proposed for the Best Western Timber Creek Inn in Sandwich. Also, there was a second CoCo Key Water resort at the Sheraton Chicago in Arlington Heights, but that closed in 2009.

For many years, KeyLime Cove Water Paradise Resort was open in Gurnee, near Six Flags Great America. Attractions included a bowl ride, water slides, a lazy river, a wave pool, and an adults-only whirlpool. The resort closed in 2017, however. It is expected that a Great Wolf Lodge indoor water park resort will open in its place.
