Your family's summer will come alive at Waterworld California, and the kids can play for half price everyday. Laugh and scream together on the Big Kahuna, the area's largest tube slide. Bodysurf in Northern California's largest wave pool. And float down the region's longest lazy river. It's the ultimate H20 action, with more slides and attractions than any other water park in California. And, since it's just about a minute from I-680 and Highway 242, it's close enough for a whole day or afternoon of fun for the whole family.
