One of the main attractions in the big Norwegian city Bergen is the Aquarium. In more than 60 aquariums you can watch in fascination all creatures from Scandinavian coast. Also you can move through a water tunnel, under sharks and other wonderful fish. Close to the entrance you can see penguins and sea lions. Other attractions are tropical and reptail sections. It is placed in  Nordnesparken, surrounded by sea on three sides and is within walking distance of the centre of Bergen.
My opinion is Bergen aquarium is worth a visiting.
