Trust that the drive to the southland will be worth your while: This 360,000-square-foot water park ($7 for residents, $14 for nonresidents) includes five slides (the longest—328 feet), sand volleyball courts, a pool with a zero-depth entry, and a cliff jump. And, yes, the concession stand sells typical poolside fare (nachos, hot dogs). But it also whips up housemade Italian ice. (Try the mango.)
