Wet 'n Wild Las Vegas closed in 2004. The company says that it may reopen in a different Las Vegas location. For now, you can read the About Theme Parks Guide review and overview of the shuttered park. Las Vegas is a bizarre anomaly--an oasis of neon decadence in the middle of the desert-- and Wet 'n Wild is an odd juxtaposition within this bizarro zone: an ode to water fun where water is as scarce as a slot machine jackpot. When the mercury soars above 100 degrees, as it routinely does in the summer, the park is indeed an oasis. Like its Wet 'n Wild brethren in Orlando and elsewhere, the Vegas water park includes a great assortment of attractions and a few that may scare the pants, um bathing suit, right off of you.
