For the purpose of these lists, I consider splash pads, spray parks, and fountains to be smaller areas without a pool that kids can splash around for free or a minimal fee.
Ty Warner Park Spray Park
700 Blackhawk Drive
Westmont, IL 60559
great spray park surrounded by a sandy area and parks, can get busy but there are picnic tables and umbrellas if you can snag one.
Burr Ridge Village Center fountain
701 Village Center Drive
Burr Ridge, IL 60527
perfect for little kids, little fountains spraying from the ground allows kids to run through the water or fill up buckets- whatever they feel like doing after some great shopping there is a grassy area where you can set up a blanket and it’s a little known spot so it’s calm and peaceful. don’t get your hopes up, it’s not huge and exciting, but kids absolutely love it.
Cermak Family Aquatic Center
7600 W Ogden Avenue
Lyons, IL 60534
lazy river, a large pool with a tunnel slide, sprays and dunking buckets and a splash pad with a toddler slide and assorted water works
200 S. Lindsey Lane
Bolingbrook, IL 60440
this one has a parent tot play time for kids 7 and under, so I’m going to include it in both lists. it’s earlier in the morning so you can go before nap time, it’s cheaper than regular admission and you don’t have to deal with protecting your little one from the rowdy older ones.
The Oak Brook Park District Family Aquatic Center
1450 Forest Gate Road
Oak Brook, IL 60523
although this one has a pool and a slide, I would consider it more a splash pad than a water park
Intersection of Willow Springs Road and Hillsdale Road
Countryside, IL 60525
splash pad with adjacent park
I would say that this spray park is not for toddlers and babies, more for older children (maybe starting at 4 or 5 years old?) because the water comes our with fairly high pressure
Congress Park & Elm Avenues
Brookfield, IL 60513
