Lotte World Aquarium

The route was built around one oversized climax

Lotte World Aquarium opened on October 16, 2014 as part of the new Jamsil mall complex. Its original plan used both B1 and B2, with a roughly 840-metre route divided into 13 zones that move from Korean and tropical rivers toward open-ocean habitats

The physical climax is still the main tank. Its viewing face is 25 metres wide, followed by a long underwater tunnel where sharks and rays move overhead. That sequence gives the aquarium a clear sense of scale: smaller river and coastal habitats prepare the route for one large marine room rather than competing with it from the start

The animal-care program is unusually visible

The daily schedule goes beyond feeding shows. The aquarium currently runs a sea-lion medical briefing that demonstrates health checks based on cooperation between keepers and animals, plus an otter talk that explicitly includes behavioral enrichment—objects and activities intended to encourage natural movement and play

Other programs make the backstage work even more concrete. A children’s veterinary experience uses a rescue-and-treatment scenario, while a separate Secret Tour takes visitors into staff work areas and behind the tanks. The sea-lion and otter briefings sit in the regular ecology-talk schedule, while the veterinary activity and Secret Tour are listed separately as Experience programs. Paid experience programs are charged on top of admission, so booking and fee details need to be checked separately. The result is that husbandry appears as part of the public program rather than something happening invisibly after closing time

Bella makes the conservation story harder to simplify

Beluga whales were part of the aquarium from its opening period. After two of the original three died, Bella became the only beluga remaining at Lotte World Aquarium. In 2019, Lotte announced plans to move her out of the tank; later statements set 2026 as a target for transfer to a sanctuary or other release process

That plan proved much harder than the announcement suggested. By January 2026, most external members of Lotte’s release-technology committee considered overseas release or sanctuary transfer realistically difficult after years of searching for a suitable destination. Lotte said it had not abandoned the goal and was continuing to look for a safe option. The dispute also entered the courts. In May 2026, an appeals court upheld the offenses of a marine-environment group representative who had protested at Bella’s tank but suspended the fine, citing the public-interest aim of animal protection and saying Bella’s exhibition appeared to conflict with her ecology and habits; the case ended later that month when no further appeal was filed

The Bella case is part of the visitor story. An aquarium that now teaches medical care, enrichment and marine rescue also carries a very public unresolved case about what long-term care should mean for a large Arctic whale in captivity. The tension is worth knowing before treating the education program as a simple conservation narrative

Jamsil makes it easy to build a larger day

The aquarium sits inside Lotte World Mall at the base of the tower complex, directly connected to Jamsil Station. That makes it one of Seoul’s easiest aquariums to combine with another major attraction: Seoul Sky is in the same complex, while Lotte World Adventure and Seokchon Lake are nearby

Because the aquarium itself is a substantial indoor visit, pairing it with one other anchor usually makes more sense than trying to stack every Jamsil attraction into the same day

Before you go

Ecology talks and feeding sessions change the character of the visit more than most optional add-ons, so checking the day’s schedule is useful before entering. The main tank and animal-care programs are on B2, after the earlier river and coastal zones, which means arriving shortly before a scheduled talk can affect how quickly the first half of the route needs to be covered
