This north county park, dedicated in 1995, pairs its splash fountain play area with a playground, paved fitness trail, and basketball courts. St. Louis County Parks runs the fountain at no charge on regular park hours.
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.
