COEX Aquarium is one of the must visit places in Seoul which is open throughout the year. The tour may take around 1 to 1.5 hours and visitors are allowed to take photos without restrictions. It is rather hard to enjoy and learn about the nature in an urban city like Seoul. However, COEX Aquarium offers you an amazing opportunity to explore and unfold the ultimate mystery of sea world, especially for those who love sea animals and are interested to learn about their habits and behaviours. 
COEX Aquarium is renowned as the best domestic marine theme park and also referred to as the "Classroom under the sea". Visitors can learn about marine education and have fun at the same time. The "Journey of water" comprises of 12 different areas as shown in the photo.
With that largest scale, COEX Aquarium is said to hold more than 40,000 sea creatures of 650 kinds with 3,000 tons of water. It has adopted the concept of Edutainment perfectly, combining entertainment plus education together. Visitors will get to explore the diversity of sea world as you journey through the aquarium. At the end of the "Journey of water", you can also find snack bar for snacks and drinks, and a souvenir shop selling various items of sea creatures.
The most exciting display was Ocean Kingdom and Undersea Tunnel where explorers get the fantastic view of 180 degree tunnel with very rare sea living things including 10 huge sharks. Polar bears can also be viewed on some lucky days.
