The Tropical Islands resort, just south of Berlin, Germany, is an old abandoned aircraft hangar that was transformed into an indoor water park. The theme park, which is 66,000 square feet in size, includes several swimming pools, a four-story tall water slide, a tropical lagoon, themed cabins (including modern and adventure-themed rooms), medicinal saunas and steam baths, a mud bath spa, a meditation room, and the largest indoor rain forest in the world. Buildings are created in the styles of several different cultures, including southeast Asian, Spanish, Native American, Brazilian, Cambodian, and Australian Aboriginie.
