Local tips

  • Time your visit to coincide with a scheduled feeding session; the tanks come alive and staff explanations make the behavior and adaptations of local species much easier to understand.
  • If you are visiting with small children, plan extra time at the dedicated kids’ touch pool and outdoor Water Laboratory, where supervised handling of crabs and starfish is encouraged.
  • Check in advance for porpoise or tuna safari departures; places are limited and trips are weather dependent, but they add a memorable open-water dimension to the aquarium experience.
  • Combine the aquarium with a walk along the seafront to Kronborg Castle to appreciate how closely the exhibits mirror the real marine habitats just off the shoreline.
  • Wear layered clothing and sensible footwear if you plan to spend time at the outdoor Water Laboratory or join a boat trip, as wind and spray can make conditions feel cooler than in town.

Getting There

  • Train and walk from central Helsingør

    From Helsingør Station, the aquarium is roughly 1–1.5 km away, which usually takes 15–20 minutes on foot along generally flat, paved routes suitable for strollers and most mobility levels. Regional trains connect Helsingør with Copenhagen and other Zealand towns several times per hour, with typical one-way fares from Copenhagen in the range of 80–120 DKK in standard class. Services run throughout the day, but late-evening frequencies are lower, so it is worth checking return times if you plan to stay until closing.

  • Local bus within Helsingør

    Several local bus routes link Helsingør Station and nearby neighborhoods with stops within walking distance of the harbor area north of Kronborg, from where it is a short walk to the aquarium. Travel times are usually 10–20 minutes depending on route and traffic. Single tickets within the local zone generally cost about 20–30 DKK when bought from machines or via transport apps, and buses run at reduced frequency in the evenings and on weekends, so allow extra time outside weekday daytime hours.

  • Car access and nearby parking

    Drivers can approach Helsingør via major regional roads and follow signs toward the harbor and Kronborg Castle area, where the aquarium is located nearby on the waterfront. Public parking is available in paid car parks such as facilities a few minutes’ walk from the aquarium, with typical rates in Helsingør around 12–20 DKK per hour during the day and possible free or reduced tariffs in the evening. Spaces can fill up during school holidays and summer weekends, so plan a little extra time to find a spot.

  • Ferry from Helsingborg and onward by foot

    If you are coming from Helsingborg in Sweden, frequent ferries cross to Helsingør in about 20 minutes, with pedestrian return fares commonly in the 90–140 SEK range depending on time and ticket type. From the ferry terminal in Helsingør, the walk to the aquarium typically takes 15–20 minutes along level harbor paths. The crossing operates year-round with shorter intervals at peak times and slightly longer gaps late in the evening or early in the morning.

A small aquarium with a big local focus

Øresund Aquarium is a compact saltwater aquarium set right on the waterfront north of Kronborg Castle, focused entirely on the marine life of the Øresund strait. Instead of far‑flung tropical species, its tanks showcase the fish, crustaceans and invertebrates that actually live in Danish and nearby Swedish waters. This sharp local focus makes the collection feel surprisingly distinctive, turning what could be a modest aquarium into a window onto the sea just outside. Inside, you move through a series of biotope and theme aquariums arranged to mirror different habitats: stone reefs, sandy seabeds, eelgrass meadows and darker, deeper areas. Cold‑water fish glide through kelp, eels weave between rocks, and shy bottom‑dwellers lurk half‑hidden in the sand. Clear labeling and simple explanations in accessible language highlight how salinity, depth and currents shape life in the strait.

Hands-on encounters with Nordic sea life

One of the defining experiences here is the set of touch pools designed for different ages and comfort levels. A dedicated children’s pool keeps the animals within easy reach of small hands, with hardy species such as crabs, starfish and flatfish that can cope with gentle handling under staff supervision. Nearby, a deeper touch tank aimed at older visitors lets you get closer to rays and small sharks, offering a rare tactile experience of northern marine species. Throughout the day, staff‑led feeding sessions bring extra life to the tanks. Animals emerge from hiding to chase food, while marine biologists narrate behaviors, adaptations and ecological roles. These sessions turn brief observations into stories, whether about how a flounder changes color to match the seabed or how schooling fish avoid predators. For many visitors, this direct, guided contact with local sea life is the highlight of a visit.

The outdoor Water Laboratory by the harbor

Just a short stroll from the main building, the aquarium operates an outdoor Water Laboratory set in the harbor area. Here, a large basin is constructed as a miniature slice of Øresund, complete with stone reefs, sandy patches and seaweed beds. The water is open to the elements, and new animals are regularly introduced, so the micro‑ecosystem is always changing. This outdoor zone blurs the boundary between exhibit and nature. You can watch crabs patrol the stones, small fish dart through strips of kelp and sea anemones sway in the current. It is particularly atmospheric on calm days, when reflections of boats and sky ripple above the submerged habitats. The Water Laboratory is used for seasonal activities such as crab‑catching events and demonstrations, giving families a playful but structured way to explore the strait’s biodiversity.

Research roots and conservation mission

Øresund Aquarium is part of the University of Copenhagen’s Department of Biology, and this academic connection shapes its character. Beyond display tanks, the site functions as a knowledge hub for the local marine environment. Staff use the aquarium as a platform for school programs, lectures and field‑based teaching, translating current research into engaging, tangible experiences for children and adults. Conservation threads through much of the interpretation. Exhibits and talks emphasize why the Øresund strait is ecologically special, with its mix of brackish and more saline water and its importance for fish, seabirds and marine mammals. The aquarium is actively involved in projects that aim to protect local habitats and communicates simple, practical ways visitors can reduce their impact on the sea, from seafood choices to shoreline behavior.

Sea safaris and seasonal activities on the Sound

The aquarium extends its reach out onto the water with guided boat trips on Øresund. On these small‑group excursions, marine guides help you look for harbor porpoises, Denmark’s smallest whales, as well as seasonal visitors such as Atlantic bluefin tuna and flocks of seabirds. These safaris highlight the dynamic, larger‑scale life of the strait that cannot be brought into tanks. On land, school holidays bring extra activities ranging from special touch‑an‑animal sessions to dissections and themed events. Indoors remains compact enough to explore in an hour or two, making it easy to combine with Kronborg Castle or a harbor stroll. Together, the aquarium, Water Laboratory and boat tours create a layered introduction to Øresund: intimate, educational and firmly rooted in the local sea right outside its doors.
