Splash pads in Peoria, Illinois

Glen Oak Park is Peoria's signature park and the splash pad is the cool-down centerpiece of a campus that includes the Peoria Zoo, the Luthy Botanical Garden, and a sprawling destination playground. Ground sprays for toddlers, arching jets for older kids. Free parking, clean restrooms. Parent gotcha: central-Illinois summer storms can roll in fast off the prairie — check radar; the pad closes during lightning. Best on weekday mornings paired with a zoo visit (paid, but excellent). Pack a picnic. The most museum-and-zoo-rich Peoria afternoon you can have. Quintessential downstate-Illinois summer.
