According to Disney legend, Disney’s Typhoon Lagoon was created by an epic storm. Surfboards were hurled into palm trees and boats were tossed around like toys.

The typhoon made the storm-soaked Mount Mayday an ideal source for exhilarating waterslides. Surrounding the mountain, a 56-acre topsy-turvy tropical paradise was formed—full of waterways, rivers, rapids and slides.
