Den Blå Planet: A Hands-On Aquarium Near Copenhagen Airport

What the reviews show

Den Blå Planet is an aquarium in Kastrup, Denmark, with a strong public reputation: it holds a Google rating of 4.4 from 21,653 reviews. Traveller feedback consistently describes a clean, well-maintained venue with plenty of marine life to see. The displays are organized by natural habitat regions, which several reviewers found easy to follow.

The aquarium appears to work especially well for families with young children. One review describes a successful morning with a toddler, while another says a four-year-old had enough to keep them interested. The layout offers a clear route through the exhibits, and the venue combines indoor displays with an outdoor butterfly area and sea-facing outdoor seating.

What stands out

The range of animals is the main draw. Reviewers mention a particularly memorable Arapaima gigas, a large freshwater fish known for surfacing to take air. Prehistoric displays also add variety beyond the tanks. The interactive elements receive strong praise, including opportunities to touch fish and sting rays.

That hands-on quality gives Den Blå Planet more energy than an aquarium built only around viewing tanks. It can be engaging for children and appealing to adults who enjoy unusual species. One reviewer ranked it among the best aquariums they had visited, while another felt it was not among the world’s very largest. Expectations matter here. This is a manageable attraction rather than an all-day mega-aquarium.

Planning the visit

Location is a practical advantage. Public reviews describe Den Blå Planet as one metro stop from Copenhagen Airport, with straightforward metro access from Copenhagen Central Station. That makes it a possible stop for travellers with time near the airport, as well as a half-day outing from Copenhagen.

Crowding is the main issue raised in the feedback. Narrow walkways can feel uncomfortable when visitor numbers rise, and one reviewer found the aquarium far too crowded. A Monday afternoon visit was described as calm, suggesting that a quieter weekday period may improve the experience, though public reviews cannot guarantee conditions on a particular day.

The cost is another point to consider. One reviewer considered the admission expensive, and cloakroom use requires a paid charge with a refundable deposit. The restaurant receives a positive mention for fish and chips, with outdoor seating facing the sea, but visitors focused on value may want to plan around the admission cost.

Verdict

Den Blå Planet suits families, aquarium enthusiasts and travellers looking for an accessible attraction near Copenhagen Airport. Its strongest features are the organized habitats, interactive encounters and memorable species such as the Arapaima gigas. The experience is less convincing for visitors expecting a huge aquarium or a spacious route during peak periods.

The public feedback points to a well-kept, thoughtfully arranged venue that can fill half a day. Going at a quieter time should make it easier to take in the exhibits without being pushed along. For many visitors, especially those with children, that is enough.
