2 free pads in St. Louis
Citygarden Splash Plaza
Citygarden is the most underrated free downtown family stop in St. Louis — a sculpture park where the interactive water jets, spray plaza, and shallow wading basin are all open for kids to run through, with massive Niki de Saint Phalle and Mark di Suvero pieces as backdrop. The pad is generous, sized for both toddlers and big kids, with arching jets and ground sprays. Paid garages ring Market Street; metered spots are easy on weekends. Parent gotcha: the granite plaza heats up by midday and there's almost no shade — go before noon or pack umbrellas. Walk to the Arch grounds after. STL's best free hour.
Forest Park Visitor Center Splash Pad
Forest Park is bigger than Central Park and the splash zone near the visitor center is the perfect anchor for a full STL family day — pair it with the free zoo, the free Art Museum, and the Boathouse for paddleboats. The pad has gentle ground sprays sized for toddlers and early grade-schoolers. Free parking is plentiful but fills near the zoo by 10:30am — park near the visitor center instead. Parent gotcha: the park is huge and signage is uneven; pin your destinations before you leave the car. Pack a cooler for the pavilions. The single best free family day Missouri offers, full stop.
