Knights Action Park

Just a short drive from the Tri-States Knights Action Park is located in Springfield, Illinois and this water park has it all. Including a waterslide that all thrill-seekers must try the "Royal Flush." Then when you're done go play putt-putt, see a drive-movie, and the small amusement park all part of Knights Action Park.

Six Flags Great America

Both a waterpark and amusement Six Flags Great America is the perfect thrill-seekers park. You will get both extreme coasters and extreme waterslides all in one park. I've never been to this Six Flags park, but it's on my future bucket list to make a trip to Gurnee, Illinois, and see what the amusement park is all about.

Raging Waves

This waterpark has a total of 19 waterslides for visitors to try which makes this park the largest waterpark in the entire state. From the littles in your family to the bigs there is something for everyone. You can spend so much time at this one park you might have to make a weekend visit out of it.

The Water Works

Located in Schaumburg, Illinois is an indoor waterpark so you won't have to worry about getting that summer sunburn. Water Works has three waterslides, a rapid water channel, sprayground, diving pool, lap pool, and more.
