Den Blå Planet, National Aquarium Denmark
Experience life beneath the surface

Next to Copenhagen Airport and the first metro stop Kastrup, you’ll find Northern Europe’s largest aquarium, Den Blå Planet.

The award-winning architectural building draws its guests beneath the surface. Immerse yourself in an unforgettable experience with over 23,000 animals.

With 7 million liters of water and 727 species, Den Blå Planet, National Aquarium Denmark, is an attraction for all ages. Visitors don't just walk along the glass walls; they step into an underwater universe where all senses are brought to life.

Experience the thrill as sharks swim over your head in the enormous Ocean Tank. Roll up your sleeves and assist in feeding the cownose rays or explore the Rainforest, spotting birds, insects, and sloths.

Den Blå Planet is one of the few places in Europe where you will find sea otters. All the sea otters at the aquarium have been rescued in the wild because they got separated from their mothers or were injured.

In the large Ocean Tank, you can experience Azul: A sea turtle that mistakenly ended up in the cool Danish waters and now resides at Den Blå Planet. The aquarium has a mission to ignite people's interest in marine life and raise awareness of its fragile state.


During the summer months, you can enjoy outdoor activities such as a water playground and The Wild Pond.
