Maryland Heights' municipal water park offers a FlowRider surf simulator, lazy river, flume slides, and a Cardinals-themed kids area at small-city prices ($7 resident adults, kids 3 and under free). Nonresident admission roughly triples the rate.

What's on site. OpenStreetMap maps toilets on site, drinking water, playground alongside, parking at this location.

When to go. Peak summer highs in Maryland Heights average 89°F — warm enough for a splash pad through most of the season without being punishing at midday.
