Gothenburg Maritime Museum and Aquarium: What to See
Gothenburg's Maritime Museum and Aquarium, Sjöfartsmuseet Akvariet, is the one to pick if you want living exhibits rather than ships: its underground Aquarium Hall holds 15 aquariums, including a 400,000 litre tank with a living coral reef. Allow around two hours for the aquarium hall and the Ocean Lab, and treat Maritiman at Packhusplatsen as a separate museum with its own ticket.
This guide covers where the museum sits on Karl Johansgatan, its published opening days, what is inside the Aquarium Hall and Korallhavet, how long to budget, and why the floating ship museum down at the harbour is a different outing.
Where the museum is on Karl Johansgatan
The museum's address is Karl Johansgatan 1–3 in Göteborg, on the flat grid of streets west of the city centre rather than on the waterfront. That places it in a quiet residential stretch within walking distance of the tram and bus stops along the same street, so you can arrive on foot from the centre without needing a ferry or a long detour.
Because it sits off the main sightseeing circuit, it works best as a single focused stop rather than part of a dense walking route: pair it with one nearby park or viewpoint and leave the rest of the day free. If you are building a wider short break, the rest of the city's named sights are mapped in our Gothenburg Attractions: 21 Visitor Guides, which makes it easier to slot the aquarium in without crossing town twice.
Opening days and times through the week
The museum closes on Mondays. From Tuesday to Friday it opens at 10am, closing at 6pm on Tuesday, Wednesday and Thursday, while Wednesday runs late to 8pm; at weekends it opens at 10am and closes at 5pm on Saturday and Sunday, with the same 10am–5pm window on Friday. Check these published hours before travelling, since seasonal schedules are not fixed.
The Wednesday late closing is the most useful slot on a short city break: it lets you spend the daylight hours outdoors and still get a full aquarium visit in the evening. A Tuesday or Thursday visit, by contrast, needs to start by mid-afternoon to leave enough time for both the Aquarium Hall and the Ocean Lab.
What the Aquarium Hall holds: 15 aquariums and the 400,000 litre reef tank
The Aquarium Hall sits underground, with the world ocean as its theme, and displays 15 aquariums arranged as different ocean biotopes rather than a single row of tanks. Several are cast in situ, and the largest of them holds 400,000 litres around a living coral reef, which is the centrepiece of the hall.
Interactive stations sit alongside the tanks, so the hall suits children who need something to press and read rather than only glass to look through. Plan to move slowly here: the biotope layout rewards reading the labels in sequence instead of hurrying past the smaller tanks to reach the big reef.
Korallhavet and the living coral collection
Korallhavet, the Coral Sea, is where the museum shows endangered stony corals and explains how a reef builds up over time. It is described as one of Europe's largest aquariums for live corals, and it doubles as a living gene bank rather than a purely decorative display.
If your interest is marine biology rather than ships, this is the reason to choose this museum over the harbour's floating exhibits. Give the coral section its own unhurried slot, then work back through the other biotopes.
The Ocean Lab: research, petting tanks and lab benches
The Ocean Lab is a public marine research laboratory within the museum, built around lab benches, experimental aquariums and petting tanks that let visitors handle and explore sea life directly. It also presents the aquarium's own research, including coral cultivation, and gives visitors the chance to take part in research projects.
School classes use the lab, so it can be busier at certain times, but the hands-on format is what separates a family visit here from a conventional museum cabinet display. Budget a solid stretch of time for it rather than treating it as a corridor between tanks.
How much time to allow for the museum and aquarium together
Two hours is a realistic allowance for the Aquarium Hall, Korallhavet and the Ocean Lab at a comfortable pace, and a little more if you read the research displays properly. That fits neatly into a one- or two-day Gothenburg trip without eating the whole afternoon, and the Wednesday evening opening makes it even easier to squeeze in.
If you are planning the wider trip around it, our things to do in Gothenburg guide shows how a museum stop sits alongside the city's squares, waterfronts and parks. Keep the visit as one block rather than splitting it, since the underground hall works best seen in sequence.
Maritiman, the floating ship museum at Packhusplatsen
Maritiman is a different museum altogether: a floating collection of ships and boats moored at Packhusplatsen 12 in Göteborg, with a separate admission from the aquarium. Its 2026 season runs programme days with guided tours and children's activities and cheaper base days when you explore the ships at your own pace, so the ticket you buy depends on the date you pick.
For 2026, its published summer season runs from 13 June to 31 August with a 10am to 8pm day, and on Midsummer Eve it closes early at 2pm; spring and autumn weekdays are base days at a lower admission. Treat those dates as this year's schedule rather than a permanent pattern, and choose the aquarium instead if you want corals and sea life rather than engine rooms and decks.
What to check before you travel for tickets and seasonal changes
The Maritime Museum and Aquarium sets its own admission, so confirm the current price, any concessions and whether booking ahead is needed on its own ticket page before you go. The same applies to the Maritiman, where the base day and programme day structure means the fee changes with the date, and spring and autumn weekdays cost less than programme days.
If you have time for a second green stop, the botanical garden at Göteborgs Botaniska trädgård is a relaxed counterpoint to the dark aquarium hall. Closer by, Slottsskogen, Gothenburg's large park, has open lawns and makes an easy pairing on a dry day.
Aquarium or floating ships: which to book?
Book the Maritime Museum and Aquarium if you want living corals, a 400,000 litre reef tank and hands-on lab space in a single underground hall; it is the stronger choice for families and for anyone on a tight two-day schedule, especially on a Wednesday when it stays open until 8pm.
Choose Maritiman instead if you would rather walk the decks of real ships at Packhusplatsen and are willing to plan around its programme and base days. Whichever you pick, build the day around one museum and one outdoor stop, and finish with a climb to Skansen Kronan, Gothenburg's hilltop fort, for the view over the rooftops.

Frequently Asked Questions
Is the Gothenburg Maritime Museum the same as Maritiman?
No. The Maritime Museum and Aquarium is on Karl Johansgatan 1–3 and holds the Aquarium Hall and the Ocean Lab. Maritiman is a floating museum of ships moored at Packhusplatsen 12, with its own admission and its own programme and base day schedule. In 2026 its summer season runs from 13 June to 31 August, opening 10am–8pm apart from a 2pm close on Midsummer Eve.
Do you have to pay to go to the maritime museum?
Yes. The museum sets its own admission, so confirm the current fee and any concessions on its own ticket page before you travel. Maritiman charges separately for its ships, and its spring and autumn weekdays are cheaper base days at a lower admission than programme days.
