The National Aquarium Denmark (also known as Blue Planet or Den Blå Planet) is one of Northern Europe’s largest aquariums, with over 20,000 marine mammals and fish housed within its sleek modernist facade. Designed to resemble a whirlpool when viewed from above, the structure is set on the banks of the Øresund straight.
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.

An Architectural Highlight
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.
