Alton's splash pad sits right on the Mississippi riverfront, so kids cool off with barge traffic and the Clark Bridge as the backdrop. Hours are shorter than most pads, ending at 5 p.m.
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 Alton average 87°F — warm enough for a splash pad through most of the season without being punishing at midday.
