Aquaplanet Yeosu: Meet a Beluga at Expo Ocean Park

Hi, I'm Sudal, your otter guide to Yeosu. Today I want to step away from downtown for a bit and head over to the Expo Ocean Park area. There's one place that almost always comes up when people are planning a Yeosu itinerary: Aquaplanet Yeosu. A lot of visitors wonder why a coastal city would need a big aquarium of its own, so today I'll walk you through what I know, along with the parts of the story that are told a little more carefully.

A big aquarium inside Expo Ocean Park

Aquaplanet Yeosu is known as a large aquarium located inside Yeosu Expo Ocean Park. With 'Yeosu' right there in the name, it's hard to talk about this place without talking about the city itself. It's often said to have been built around the time of the 2012 Yeosu World Expo, as part of everything that came together for that big event. These days, even visitors who don't know much about that history still end up adding it to their Yeosu trip without a second thought.

That said, I want to be careful here — exactly when it opened and how large it really is tends to be told a little differently depending on the source, so I won't pin down an exact year or size. What does seem consistent is that it's remained one of the signature facilities of Expo Ocean Park for a long time. Even locals who grew up in Yeosu tell me they've visited at least once, so it's a name that shows up often in both memories and travel photos.

Known as a place to meet a beluga

When people talk about Aquaplanet Yeosu, the beluga almost always comes up. It's often introduced as a place where you can get close to large marine animals like the beluga whale. Standing in front of the glass and looking up at such a big creature really makes you feel how vast and full of life the sea can be. I think it might be the first image a lot of travelers picture when they hear the name Aquaplanet Yeosu — families with kids and friends visiting together all seem to stop right there for a good long look.

I can't say for sure exactly how many animals are there or exactly which species are on display at any given time, since that kind of thing can change. So if you're curious about the details, I'd recommend checking the latest information before you go. Still, the story that keeps coming up is that this is a place to meet large marine life, and every time I hear it, it reminds me how many different faces Yeosu's sea can have.

A route that pairs naturally with Yeosu Expo Station and Expo Ocean Park

Aquaplanet Yeosu sits close to both Yeosu Expo Station and Expo Ocean Park, so a lot of visitors combine them into one trip instead of treating them as separate stops. Get off at Yeosu Expo Station by train or bus, start walking toward the park, and you'll naturally find yourself heading straight into Aquaplanet Yeosu. It's a route where you walk along the sea and then step into a cool indoor aquarium, which makes it easy to plan around hot days or sudden rain.

I've done this myself — got off at Yeosu Expo Station, took a full loop around the park, and then walked straight into Aquaplanet Yeosu without needing to call a taxi or figure out directions along the way. Breathing in the sea air while cooling down on the walk, then stepping into the cool indoor space at the end, turned out to be a nice little rhythm. If you're looking to combine the sea and an aquarium into one day trip in Yeosu, this route alone is worth remembering.

A good backup plan no matter the weather

Yeosu is a coastal city, so blazing summer sun or sudden monsoon rain can throw off travel plans pretty easily. Having a spot like Aquaplanet Yeosu, where you can cool off indoors, makes things a lot less stressful. From what I hear, a lot of visitors walk through Expo Ocean Park and duck inside to see the beluga and other marine life when it gets too hot or starts raining, then head back out once the weather clears. Families with kids especially seem to like being able to move between indoor and outdoor spots at their own pace. Next time I'm in Yeosu, I think this is the route I'll reach for first, rain or shine.
