Raging Waves Yorkville is open for the 2026 season, giving Chicago-area families a Memorial Day weekend option with slides, a wave pool, a lazy river and children’s play areas.

The Illinois water park opened its holiday weekend schedule after a one-day delay caused by cold temperatures, according to information from Raging Waves. The park’s official schedule lists operating hours from 11:00 AM to 5:00 PM CT on Saturday, May 23, Sunday, May 24, and Monday, May 25, 2026.

Heated Water Added to Wave Pool and Lazy River

The update gives the Yorkville destination a stronger family-travel angle for early summer, especially for visitors searching for an Illinois water park near Chicago with attractions for children and adults.
