Planning a family trip to South Korea and wondering if the newly renovated SEA LIFE COEX Aquarium in Seoul is worth your time? If you have ever been to a Sea Life location next to a Legoland in the US, you might think you know what to expect—but the Seoul location is in a completely different class. Located deep inside the iconic Starfield COEX Mall in Gangnam, this massive urban aquarium just underwent a massive multi-million dollar rebranding and structural glow-up, making it a premier destination for multi-generational families.
In this narrative-free, highly cinematic walkthrough, we take you through all 14 themed zones, from the stunning Amazonian river ecosystems to the breathtaking underwater shark kingdoms. We’ll give you a first-hand look at the massive new upgrades, including the expanded Seal Beach Cove, the Secret Garden of Seahorses, and the incredible Glass Bottom Boat experience over the main shark tank! Whether you are looking to escape a rainy day in Seoul or wanting a relaxing, visually beautiful activity that both elderly parents and toddlers will love.
While Merlin Entertainments initially acquired the iconic site back in April 2022, they spent over three years planning and executing a massive multi-million dollar refurbishment. The grand 2025 transformation is what introduced the premium experiences you caught on camera, such as the immersive "Sea at Night" digital media art zones, the upgraded floor-to-ceiling "Seal Beach Cove", and the mystical "Secret Garden of Seahorses
Q: Is the Sea Life Aquarium in Seoul part of the Lego company?
A: You hit the nail on the head! It actually shares the exact same parent company, Merlin Entertainments, which owns and operates all the global LEGOLAND resorts and discovery centers. They took over the legendary COEX Aquarium a few years back and integrated it into their world-class Sea Life network, which is why the corporate branding feels so familiar!
Q: I've been to the Sea Life locations in California and Florida. Is the Seoul one any different?
A: Honestly, it is on a completely different level. The ones back home in the US are fantastic, but they're typically smaller indoor attachments built right next to the theme parks. The COEX location in Seoul is a massive, flagship premier city-center aquarium with 14 huge themed zones. It feels much more premium, deeply immersive, and boasts massive ocean tanks that dwarf the domestic versions.
Q: Where exactly is the aquarium located and how do we get there?
A: It is located right inside the giant Starfield COEX Mall in the Gangnam district. The easiest way to get there is by taking Seoul Subway Line 2 to Samseong Station. Once you head inside the mall, just follow the clear English signs directing you past the famous Starfield Library—the aquarium entrance is just a short, indoor stroller-friendly walk from there.
Q: Should I buy tickets at the door or book them ahead of time?
A: I highly recommend booking your tickets ahead of time using an app like Klook or Trip.com. Not only do you get to entirely bypass the main ticket sales queue at the front gate, but the online prices are significantly cheaper than paying walk-up gate prices, which easily saves our family cash for snacks later!
Q: Is the aquarium a good option if we are traveling with elderly parents or toddlers?
A: It's perfect for both. Because the entire facility is completely indoors and climate-controlled, it's the ultimate escape from hot summer humidity or a sudden rainy day in Seoul. The walkways are incredibly wide, completely flat, and fully wheelchair and stroller-accessible, meaning Grandma and the little ones can pace themselves without getting worn out.
