Den Blå Planet, Copenhagen Travel Guide

Den Blå Planet's distinctive whirlpool-shaped building is as much a work of art as the exhibits it houses. Designed to evoke the natural movement of water, the structure has become an iconic landmark in Copenhagen's rapidly evolving western district. The award-winning architecture draws visitors in from the moment they arrive, setting the stage for an immersive journey into the aquatic world. The building's design seamlessly integrates with its waterfront location, creating a sense of entering another realm entirely.

With 7 million liters of water and over 24,000 animals representing 735 species, Den Blå Planet offers an extraordinary window into global aquatic ecosystems. The Ocean Tank stands as one of Northern Europe's largest, where visitors experience the awe-inspiring sight of hammerhead sharks and other large predators gliding overhead. Beyond the main tank, themed zones transport you from tropical rainforests teeming with birds, reptiles, and a resident sloth, to Danish coastal waters where native species like crabs and flounders inhabit touch pools. Each exhibit is thoughtfully curated to educate and captivate visitors of all ages.

Den Blå Planet distinguishes itself through hands-on experiences that bring marine life to life. Daily feeding demonstrations showcase piranhas, giant arapaimas, and cownose rays, with visitors invited to participate in some feedings. The aquarium is one of the few places in Scandinavia where you can encounter sea otters—all rescued from the wild after separation from mothers or injury. Plaske, the world's only talking sea otter, performs daily at 11:00 AM in the outdoor habitat. Mini guided tours led by storytellers offer curated insights into favorite exhibits, while creative workshops and the interactive Wild Pond allow children to net and examine tiny creatures up close.

During summer months, Den Blå Planet transforms into an extended playground with a water splash area and expanded programming. Evening tickets after 7:00 PM offer a calmer, more intimate exploration at a reduced price, complete with special feeding demonstrations and guided tours. The aquarium regularly hosts themed talks connecting animals to their native countries, and in 2025 featured the Underwater Photographer of the Year exhibition—a rare Scandinavian showing of world-class ocean photography. Peak season hours extend to 9:00 PM, allowing extended exploration during busy periods.

All areas feature level access for visitors with reduced mobility, and the facility welcomes families with strollers and young children. A cloakroom provides coat and luggage storage, while Café Plankton offers dining with views across the Øresund strait. The aquarium operates 365 days a year, including holidays, with extended hours on Mondays and during peak seasons. Online ticket booking is strongly recommended, as weekends and holidays frequently sell out. Annual passes offer excellent value for repeat visitors, with discounted rates available through the mobile app.
