Xtreme Waterparks

The adrenaline-filled ride begins off the southern tip of Portugal, where thrill seekers take on one of the tallest, heart-pumping drops on the planet. The adventure continues in Louisville, Kentucky, where a spin on one of the world's first water coasters, with its snaking high bank turns, blasts riders through more than 900-feet of enclosed tunnels and thrilling hills at speeds topping 30 mph.
