America's Amazing Waterslides

Dolphin Plunge, Aquatica at SeaWorld, Orlando, Fla. SeaWorld Orlando reports the Dolphin Plunge is its most popular ride, and it's easy to see why: two clear, enclosed tubes shoot riders through a playful pod of beautiful black-and-white Commerson's Dolphins. They're known to be playful and fast – just like the ride itself. (Seaworld Orlando )
