The Metro East's biggest free splash pad sprays from arches, dumping buckets, a spider-web feature, fountains, and a play creek inside a sprawling sports park with playgrounds, trails, and public restrooms. The unsupervised pad requires adult supervision for kids under 10 and swim diapers for the not-yet-potty-trained.
