Summer is finally here and this is when the monsoon season strikes! Are you still wondering what to do on a rainy day in Seoul? Here is an awesome indoor activity for you! A visit to the COEX Aquarium would sound good, isn’t it? Keep scrolling down to find out more information about the COEX Aquarium!

About the COEX Aquarium
COEX Aquarium is located inside the COEX mall and is one of the largest aquariums in Korea, featuring over 40000 creatures and 650 species. The COEX Aquarium features 90 exhibition tanks grouped in 14 “discovery zones” including 6 themed areas. The theme zones include the Rainbow Lounge, Woori Woori Fish, Korea Hospital, Imagination Fish Contry, Amazonia World, Marine Touch Research Institute, Mangrove and beach, Coral Museum, Sea kingdom, Beautiful Marine Village, Deep Blue Square, Submarine Tunnel, Deep Sea Garden, Penguin’s Dream Garden and finally the gift shop. Visitors can experience the perfect harmony between nature, environment and people here.
What is so special about the COEX Aquarium?
It is worth mentioning that the COEX Aquarium is the largest shark habitat in Korea. The aquarium is home to over 110 sharks of 17 species. Besides, the COEX Aquarium also homes a very rare and endangered species, the herbivorous manatee which is also known as the legendary mermaid of the sea.

In COEX Aquarium, you can see all sorts of marine life being exhibited in the tanks, from the creatures of childhood memories like asiatic rice fish to the deep sea creatures like giant spider crab. You can find almost everything here!
Here, you can find the sea creatures being exhibited in various types of unique aquariums, including a traffic light, vending machine and even a toilet bowl. How creative the aquariums are! The aquarium seems to be designed with a focus on entertaining kids as the interior is full of cartoon characters and vibrant colours where children might seem to be enjoying it very much.
In addition to fish, other local animals such as birds, otters, and even penguins are also included in the exhibition area.

The layout and design of each area is very well-planned. The interior decoration was impressive as well. The mangrove area is even filled with waterfall, bird sounds and thick fog.

Highlight – The Submarine Tunnel
If I were ask to choose my favourite part of the visit, it will be the Submarine Tunnel, which is an acrylic tank containing 2000 tons of water. It was truly amazing to see huge ocean creatures like sharks, sting rays and turtles swimming in all direction (even above your head!) as you trail down the tunnel on the slow-moving walking escalator. Be sure to bring along a camera so that you will not miss the chance to take pictures at this popular spot.
There is also a themed zone called Marine Touch Lab which provides an interactive experience. You can touch some sea creatures like star fish, sea slugs and sea cucumbers if you are dare enough to do that. To my surprise, the star fish gives a really rough touch.
The doctor fish aquarium is the most unforgettable experience for me. You are allowed to put your hands in the small aquarium and the fishes will gather around your hands. These fishes help to clean the dead skin as well as providing massage on your fingers. It tickled a lot! And yes, I laughed, especially when the fishes were stuck between my nails.
Souvenir shop
Before leaving, you can stop by the souvenir shop to bring some memories home!
Someone said that the way my teeth are shown when I smile does resemble a shark. Do I?
Overall Experience
In short, I really enjoyed spending my time there. I took around three hours to explore the COEX Aquarium. Moreover, the staffs were polite and very helpful. The exhibition area is clean, spacious and well-organised, providing a good tourist experience. I would highly recommend this place for families with kids to pay a visit! It would be an excellent educational visit for the kids to learn more about marine creatures. The kids will love it!
