Splash in the wave pool, ride the lazy river, and cool off at this water park. And if you’re an adrenaline junkie, you just have to test your fear factor on Black Snake Summit; this water slide is over seventy feet tall with an almost ninety degree pitch! This water park has a total of twenty-three water slides to ride all day long. When it’s sweltering hot in the Los Angeles region, there’s always a cool hurricane at this harbor.
