National Aquarium Denmark (Den Blaa Planet)

A paradise for nature-lovers of all ages, the aquarium features hammerhead sharks, moray eels flitting over coral reefs, and crocodiles found lurking in the aquarium's tropical rain forest exhibit. Highlights include the Planet Shark exhibition, which features glass tunnels leading into the shark tank, as well as daily feeding shows and sea otter training sessions.

Visit on a hop-on, hop-off bus tour to explore at your own pace. The Copenhagen Card includes admission to the aquarium along with entrance to Denmark’s famed Tivoli Gardens and unlimited access to public transportation.

Located in Copenhagen’s Kastrup neighborhood, the aquarium is accessible by metro, car, and train. To get there via public transportation, take metro line 5A to Den Blå Planet, or catch the train to Kastrup Airport and walk. Free parking is available on-site.

The aquarium is open year-round, except on some major holidays. Tickets can be purchased ahead of time to speed up the process of admission. Wait times are longest in July and August, when Copenhagen is typically most crowded. The aquarium stays open until 9pm on Mondays, and is quiet and less crowded in the evening.

Danish architects 3XN designed the aquarium building in a striking swirling pattern, made to look like a whirlpool. The entrance to the building is the center of the whirlpool, and the building is surrounded with a reflecting pool so visitors can feel that they are truly entering the water.
