From the earliest slides to the fastest flumes and the most concentric corkscrews, waterparks get bigger, faster and more extreme with every new one that opens. And when it comes to the question of the biggest water park in the world, the contenders are truly wild!

Like bungee jumping, the invention of the waterslide is generally credited to New Zealanders, but the world’s largest water park would be unrecognisable to the early pioneers of these water wonderlands.

Although there may have been earlier examples, the world’s first water slide to have garnered any type of attention was installed at the 1906 International Exhibition in Christchurch, New Zealand. It was nothing more than a chute that skimmed the swimmer over the water. Over the next two decades, others were built at fairs and events all over the world.

The man credited with inventing the water slide as we know it today, was Herbert Sellner, an American furniture maker who created a toboggan slide where riders would skim across a lake before finally falling in. In fact it was Sellner’s innovations that helped to create today’s multi-billion dollar water entertainment industry.

Between the 1940s and the 1970s there were lots of water slides of increasing complexity at pools, lakes and beaches around the world. However, in 1977 the game changed forever.

The world’s first purpose-built water park, Wet n’ Wild, was opened in Orlando, Florida in 1977 by SeaWorld founder George Millay. Today, there are thousands of water parks all over the world and the biggest waterpark would have Mr Millay open-mouthed in amazement!
