A natural-pool-inspired splash area with geysers and fountains beside a retro playground at 31st Street Harbor in Burnham Park. Families can pair it with a swim at the adjacent 31st Street Beach on Lake Michigan.
What's on site. OpenStreetMap maps parking at this location. No public toilets are mapped here — worth knowing before you commit to an afternoon.
When to go. Peak summer highs in Chicago average 83°F — warm enough for a splash pad through most of the season without being punishing at midday.
How long it's open. Roughly 13 weeks a year, from June to August. Seasons shift year to year and municipal pads often close early for maintenance, so check before a long drive.
