Omaka Rocka is a waterslide taste of half-pipe, near-vertical thrills previously experienced only by daring skateboarders and snowboarders.  Riders speed down flumes into massive funnels, sliding high up one side and then the other, rocking back and forth, feeling a sensation of near weightlessness.  Coming out of the funnel, they’ll skim into a drenching splashdown and then find themselves wanting to do it all over again.  Riders must be at least 48 inches tall (1.22m).
