Bergen Aquarium is located at Nordnes, a part of Bergen, with a nice view over the approach to the port of Bergen. From the Fishmarket in the center of Bergen, you keep on the left hand side of the port while walking away from the market. Approximately 10 minutes later, you will find yourself at the gate of the aquarium.
Among the attractions, you find penguins, seals, snakes, spiders, crocodiles and of course a lot of different species of fishes. They have also got a shark tunnel. In June 2012 they will add another attraction – Sea Lions.
