Memorial Day Weekend Six Flags Theme Parks
Starting Memorial Day Weekend, the park is open daily all summer long! Cool off on water attractions, like Monsoon Falls, White Water Safari and The Penguin, enjoy the best wildlife presentations around; see dolphins in Drench! at Toyota Stadium, learn about dolphins at Dolphin Harbor, and you won't want to miss presentations of walruses, tigers, sea lions, and more.
With three kids' play areas, there's lots for families to do!
