This, the largest aquarium in northern Europe, offers an exciting journey below the surface of the sea. An indoor area of 10,000 m², an outdoor area of 5,000 m², 75 tanks and more than 7,000 fish and other sea animals make sure that you can spend an entire day here in the wet element. Explore the seven destinations, dive all the way down to the bottom of the sea, crawl around on a shipwreck, catch crabs with your bare hands and feel the power of nature. Pat a starfish on the back, face a seal and search for the gold of the North Sea. Big SEA experiences are waiting for you, both indoors and outdoors.
