Sea Lion Aquatic Park is on the smaller side, but still a great spot for a chill day. It’s perfect if you’re looking to relax, catch a tan, and go down a few fun slides. The 18+ hot tub is definitely a highlight — super relaxing and not too crowded if you go early. Speaking of early, make sure you get there when it opens if you want to grab a chair, because they go fast. Overall, it’s a nice low-key spot to hang out and unwind.

Even though we are not residents so it costs us extra, it's worth it. This is one of the best watercparks in DuPage, especially for the baby to kindergarten age range. We have been taking our son here since he was 6 months and at 4 1/2 he still loves it and gets excited when we turn into the lot.

Nice water park. The kids enjoyed it. It could definitely use some updating, but other than that it seemed well run and the staff was friendly.

The kids love it here. Plenty of room even on crowded days. Several water slides and multiple pools make it fun whether you have infants, toddlers, grade schoolers, etc.
