The World’s 15 Most Beautiful Hotel Swimmingpools

13 The pools of Tropicall Island Resort, Krausnick, Germany

Tropical Islands Resort, the world’s biggest indoor water park, is located in Krausnick, Germany. Originally constructed as a zeppelin hangar, the building never housed the airship it was meant for. A Malaysian company later purchased the hangar and converted it into the spectacular adventure park it is today, featuring a rainforest, beach, artificial sunlight, palm trees, and various pools. The largest of these is the 140-meter ‘Tropical Sea,’ covering an area of 4,400 square meters and designed to mimic the waters of Coral Island.
