Discover COEX Aquarium, Korea's largest underwater theme park in Seoul's Gangnam district. Home to 40,000+ sea creatures, interactive zones, and shark tunnels - a perfect family adventure!
If you're exploring Seoul and looking for a magical escape from the bustling city streets, COEX Aquarium (now officially called SEA LIFE COEX, Seoul Aquarium) offers an incredible underwater journey right in the heart of Gangnam. This isn't just any aquarium - it's Korea's largest marine theme park, home to over 40,000 sea creatures representing more than 650 species from around the globe.
What Makes COEX Aquarium Special
Located inside the famous Starfield COEX Mall, this aquarium stands out as one of Seoul's most family-friendly attractions. The facility spans an impressive area with 183 display tanks and 90 breeding tanks holding over 3,500 tons of water. What makes it truly unique is the combination of education and entertainment - you're not just watching fish swim by, you're experiencing themed zones that transport you from Korean valleys to Amazonian rainforests and deep ocean trenches.
The aquarium recently underwent renovations to enhance visitor experience with new zones and immersive displays. One of the highlights includes Korea's largest shark colony, where you can observe these magnificent creatures up close through massive viewing windows and even walk through underwater tunnels.
Getting There: Easy Access from Anywhere in Seoul
By Subway (Most Convenient) The easiest way to reach COEX Aquarium is via Seoul's excellent subway system. Take Line 2 to Samseong Station, which is one of the busiest stations in Seoul. Use Exit 5 or 6, and you'll find yourself directly connected to COEX Mall through underground passages - no need to go outside. The walk from the subway exit to the aquarium takes about 10-15 minutes through the mall.
Alternatively, you can take Line 9 to Bongeunsa Station, though Samseong Station on Line 2 tends to be more straightforward for first-time visitors.
From Incheon Airport If you're coming straight from the airport, you have several options:
- Take the KAL Limousine Bus (Line 6704) directly to COEX - it takes about 65 minutes
- Use the Airport Railroad to transfer to Line 2 at Hongik University Station, then ride to Samseong Station
- Grab a taxi for a direct ride (expect to pay around 60,000-90,000 KRW depending on traffic)
The COEX Mall even has a City Airport Terminal where you can check in for certain airlines and drop off luggage before your flight!

Pricing Current ticket prices are competitive for what the aquarium offers. Adults typically pay around 25,000-33,000 KRW, while children's tickets are slightly less. The great news for families: children under 36 months enter free when accompanied by a parent (just bring proof of age like a passport).

Exploring the Themed Zones
The aquarium is divided into multiple themed areas, each offering a unique perspective on aquatic life:

Korean Waters Learn about local marine biodiversity in this zone featuring fish and creatures native to Korean valleys, rivers, and coastal waters. It's a great educational opportunity to understand the ecosystem of your host country.
Interactive Experiences and Photo Opportunities
