Haus des Meeres is an aquarium and zoo built inside a World War II flak tower, with over 10,000 animals on 11 floors. Kids look through glass domes into the Surf Reef, dip their hands into a nibbling fish pool, pet the koi, and spot free-roaming animals in the Tropical Area.
Sharks, rays, crocodiles and flying foxes fill the other floors, topped by a roof terrace.
