An indoor water park is a type of water park that is located inside a building. An indoor water park has the ability to stay open year-round, as it is not affected by weather conditions.
History.
Some of the first indoor water parks are Tikibad at Duinrell (The Netherlands, 1984), Nautiland located at Haguenau (France, 1984), the Aqua Mundo at Center Parc De Eemhof located at Zeewolde (The Netherlands, 1980) and Alpamare (Pfäffikon) (Switzerland, 1977).
In 1985 an indoor water park was open in Edmonton, Alberta, Canada at the West Edmonton Mall. It is called the World Waterpark and is over . It was a success for the mall and remains as one of the largest indoor water parks in the world. In 1985 Aqualud opened in France. Another indoor water park in Europe was built in Blackpool in 1986. It is called the Sandcastle Water Park.
The first indoor water park in the United States known as the Polynesian Resort Hotel and Suites in the small tourist town of Wisconsin Dells, WI. The hotel opened in 1989 and the water park in 1994. It was built in an effort to make the Dells a year-round tourist destination, rather than just a summer one. Since then, the Great Wolf Lodge brand has expanded, with multiple locations in the U.S. and a single venue in Canada, at Niagara Falls. The DreamWorks Water Park, originally slated to open in late 2019, will be the United States' largest water park upon opening.
The indoor water park craze.
Since the opening of the first park, the indoor water park business has become increasingly popular, especially for Edmonton in Canada, and Wisconsin Dells in the U.S., which proclaims itself as the "Water Park Capital of the World". The Dells has five water park resorts that have at least one water park bigger than . This includes Great Wolf Lodge, Kalahari (Wisconsin's Largest Indoor Water Park), Chula Vista Resort (Lost Rios), Wilderness Territory (Wild West, Klondike Kavern, Wild WaterDome), and the Hotel Rome at Mt. Olympus. Wisconsin has the most indoor water parks in one state. Other states in the U.S., especially in the midwest, are building more indoor water parks separate or to existing hotels so they can become a year-round destination. More water parks are also being built in Canada, Europe and Asia. Tropical Islands Resort (Krausnick-Groß Wasserburg, Germany) with an area of 66,000 m² (710,000 sq feet) is currently the largest indoor water park in the world.
