Nothing says summer like a day at the water park, and with the region's largest wave pool, Northern California's longest lazy river, water slides galore and creative kids' areas, Waterworld is the place to cool off and have fun. If you dare, the new Break Point Plunge takes you six stories up, gives you a breathtaking view of the park, and then takes your breath away as it sends you plummeting on a 270-foot-long looping adventure. There's also The Big Kahuna family raft slide, the Honolulu Halfpipe tube slide and more. But there's plenty for the littlest ones to do, too. They can explore Treasure Island, a large, interactive water-powered playground built just for kids, and Lil' Kahuna's Waterworks "sprayground" featuring giant waterfall archways, fountains, geysers, water-powered seesaws and swings, tipping buckets and pint-sized watersides. However you like to beat the heat, Waterworld has you covered -- in water.
