Thanks to Tropical Islands waterpark, the tropics now can be found in the middle of Europe. Set in the largest self-supporting hall in the world, with an area equal to that of eight football fields, this indoor aquatic environment is inspired by the natural beauty of the Asia Pacific region, Africa and South America.

Operators claim the property includes the world’s largest indoor rain forest, a large spa complex — and authentic decor and architecture. When it comes to attractions, the waterpark combines adventure, fun and simple relaxation, designed for all ages. For example, there’s an 82-foot-high slide tower, multiple leisure pools, including the Bali Lagoon, and the Tropical Sea, which has a sandy beach.
