SEA LIFE Konstanz, on the harbour front, is an aquarium that takes visitors on a journey through the underwater world from the Rhine and Lake Constance to the oceans, with tanks of fish, rays, seahorses and other marine life, including a walkthrough tunnel. Ticketed admission and interactive displays make it a popular attraction for families. Conveniently located by the lake in the centre of the city, it offers an engaging insight into the aquatic life of the region and beyond.
