About National Aquarium Denmark#

National Aquarium Denmark, marketed as Den Blå Planet, is a large public aquarium near Copenhagen’s airport that presents marine life from local and tropical waters. The facility was developed in the 2010s and features several major tanks and visitor facilities designed for public education and display.

The aquarium was purpose-built as a national aquarium complex in the 21st century to replace earlier smaller facilities and to provide a modern, consolidated public marine centre. Its galleries and exhibits were developed to international aquarium standards and to support conservation messaging.

The aquarium sits in Kastrup, on the island of Amager in the Capital Region of Denmark, close to Copenhagen Airport and linked by local public transport. Its position makes it convenient for visitors arriving or departing through the airport as well as for residents of greater Copenhagen.

  • Scale and identity: Known as Den Blå Planet, the aquarium opened in the 2010s and is described as one of Northern Europe’s largest aquarium complexes, with an open-plan layout and large viewing pools.
  • Access tip: Located close to Copenhagen Airport and linked by public transport, making it a straightforward visit on an airport transit or a half-day trip from the city centre.

What to See#

  • Main tank galleries: A large public aquarium with immersive ocean and tropical tanks designed to showcase different marine environments and native North Atlantic species alongside tropical exhibits.
  • Interactive exhibits: Interactive and family-focused zones that include touch pools and displays explaining marine ecosystems and conservation issues.

Tips for Visiting National Aquarium Denmark#

  • Visit on a weekday morning or late afternoon to avoid family crowds that peak mid-day and on weekends; the aquarium is noticeably quieter right at opening.
  • Arrive by metro (Kastrup/M2) or the nearby regional transport and use the main forecourt entrance to avoid queueing at other access points on busy days.
  • Check the daily schedule for feedings and keeper talks and time your visit for the large central tanks-these presentations concentrate activity but also offer the best chance to see big species up close.
