The city's Tilles Park (not to be confused with the county park of the same name in Ladue) keeps a jet-style splash pad next to its tennis courts. Per the parks department, the splash pad cannot be reserved for private events.
What's on site. OpenStreetMap maps playground alongside at this location. No public toilets are mapped here — worth knowing before you commit to an afternoon.
When to go. Peak summer highs in St. Louis average 88°F — warm enough for a splash pad through most of the season without being punishing at midday.
