Splash Island

Splash Island is now CLOSED for the season!

Splash Island is our outdoor aquatic playground! Perfect for all ages, spend some fun in the sun with the whole family here. For the little splashers who might not be ready for the water, there is a splash pad with bubblers and jets, featuring fun aquatic animals. Enjoy our sundeck, perfect for lounging poolside with your book and bag while your kids play, with reclining chairs and overhead shade structures. Also, on the deck are a firepit and a separate covered party area.

Splash Island features a zero-depth entry pool, slides, interactive features, dumping buckets, jets, and other spray features. There are lifeguards on duty at both the indoor and outdoor pool areas.

Hours subject to change. Splash Island will be closed if the air temperature is below 70 degrees, or in the event of inclement weather. If the lightning detection system is activated, all outdoor areas must be closed until the “all clear” signal.


Summer Notice: Lightning Warning System

Oak Brook Park District’s Lightning Prediction System is in operation from April - November.

ONE PROLONGED BLAST OF THE HORN(Flashing Light ON): Immediately seek shelter in a vehicle or building, conditions are right for generating lightning. Per District rules, ALL OUTDOOR ACTIVITY MUST CEASE. AVOID: Open areas, water, tall trees, metal fences, cellular phones, and radios. Re-locating to the indoor pool is not permitted under current COVID-19 capacity restrictions. 
THREE FIVE-SECOND BLASTS: All clear signal-risk of lightning has diminished.

If inclement weather is expected, patrons will not be charged for their reservation unless they arrive at the facility, at their own risk. Refunds will not be processed due to weather closings, as we keep staff on hand and operate the facility until we know we must close. The pool will re-open if the storm passes quickly. Free passes will be handed out by the Front Desk for closings that occur in the first half of the time slot. No refunds, nor passes, will be given out if at least 50% of the time slot has been enjoyed. This policy will only be in place for instances where the facility was open and closes suddenly in response to the Thor-Guard and/or lightning while we are in the Bridge Phase. This policy will no longer be in place once DuPage County and/or Illinois are moved to Phase 5.
