You might think that the title of the world's largest indoor water park would be a moving target, as developers are always creating indoor water parks that are bigger and better than those that came before. Surprisingly, there is one venue that remains far and away larger than all others.
Largest Indoor Water Parks in North America
If you're looking for the mother of all water parks, you won't find it in North America.
Canada's enormous 225,000-square-foot Water World, located in the West Edmonton Mall in Alberta, is the largest indoor water park on the continent.
Both of these North American indoor water parks are absolutely mammoth, but they are dwarfed by the largest in the world.
Largest Indoor Water Parks in Asia
Back in the 1990s, the world's largest indoor water park was Ocean Dome, a 323,000-square-foot Polynesian-themed venue that was part of the Sheraton Seagaia Resort in Japan. Ocean Dome featured a giant indoor beach, palm trees, mechanized parrots, waves big enough for surfers, a volcano that erupted in flames, and the world's largest retractable roof, which provided a permanently blue sky even on a rainy day. The air temperature was always held at around 86 F.
The Ocean Dome closed in 2007.
Largest Indoor Water Park in the World
To visit the largest indoor water park in the world, you have to travel to Germany. Blowing all other enormous indoor water parks out of the water is Tropical Islands Resort, located near Berlin, whose indoor rainforest-like venue spans a ginormous 710,000 square feet.
The Tropical Islands dome is big enough to fit the Statue of Liberty in standing up and the Eiffel Tower lying on its side. It is the size of eight football fields, can accommodate up to 7,000 guests at a time and features a variety of attractions, restaurants, and accommodations as well as a water park with its indoor beach and water rides.
The Tropical Waters Water Park features:
Tropical Sea: This massive pool is the size of three Olympic swimming pools. There is a sandy beach area and, for little kids, a paddling area with water toys. Note that the sun shines through the transparent roof panels, so don't forget to use sunscreen.
Magical Lagoon: This themed spa-like pool features whirlpools, palm trees, Balinese huts, a grotto and a waterfall complete the perfect jungle setting.
Water Slides: The 81-foot tower at Tropical Islands features four different water slides, ranging from a tame family slide to a high-speed turbo slide where you can reach speeds topping 40 mph.
Tropino Club: This kids space offers plenty of fun for kids. Highlights include a huge climbing area; a softball arena where kids can shoot foam balls; a building zone with XXL Lego blocks; a go-cart track with mini cars; bumper boats; and air hockey tables. Note that this is an unsupervised space, so parents need to stay with their children.
Other attractions in the Tropical Islands Resort include:
- Amazonia: This year-round outdoor water-world area features Whitewater River, a 750-foot lazy river.
- Rainforest: A 2.5-acre rainforest biodome features a .6-mile trail that lets visitors explore a space that's home to 600 different varieties of plants and wildlife species that include turtles, flamingos, macaws, peacocks, and pheasants.
- Tropical Village: This collection of traditional buildings re-creates structures from around the tropics and feature restaurants and cafés serving cuisines that range from BBQ to Thai.
- Mini Golf: An 18-hole mini golf course features real greens and an original design for players of different abilities.
- Balloon Rides: Visitors can choose between riding in a tethered or free-floating balloon. The tethered balloon takes two passengers at a time and rises up to 180 feet, while a traditional free-floating balloon can accommodate the whole family and rises about 70 feet.
