Where to Get Wet Year Round

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 are a number of hotels with indoor water 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.

The following are parks that are open.

Grizzly Jack's Grand Bear Lodge

Utica, IL

The comparatively small indoor water park to registered hotel guests (and included with room rates) as well as the general public. Attractions include water slides, a lazy river, a wave pool, an interactive water play center with a huge tipping water bucket and activities for young children. The resort also includes a small indoor amusement park with a rock wall, a zip line, and other things to do.

KeyLime Cove Water Paradise Resort

Gurnee, IL

Medium-sized indoor water park is open exclusively to registered hotel guests (no public day passes are available). Attractions include a bowl ride, water slides, a lazy river, a wave pool, an adults-only whirlpool. It is located adjacent to Six Flags Great America and could be a great place to consider staying at while visiting the amusement park.
