    The experience of taking a submarine was quite fun, but the undersea views are not really great. The water was quite turbid. There were some fish and corals around. The ticket is a bit expensive. It's not a must on Jeju.

    This I would recommend if u have not be into a submarine before. It would be 5 stars! But please note that you don't really spend much time and if you are lucky u will see school of fishes otherwise the diver will use lure provided you willing to pay 5000KRW approx 5 USD

    Very good service. Easy to make and reservation and convenient to foreigners.

    It is an experience to ride on a Submarine in Jeju. Once submerged, we get to see the corals and fish of the underwater. As it was raining before, the visibility was bad. However, there was a diver to help 'bring' the fish closer to the submarine.

    Bad customer service experience overall both when exchanging for boarding tickets at the ticket office and onboard the submarine. Submarine interior was old. Nothing much to see from the route we were taken to; just lots of sand, rocks, murky waters. Coral reefs and fishes seen were just really normal. Felt cheated when the when the whole thing ended and non of my family members enjoyed themselves. I had a better experience previously with another submarine tour company when I toured in the waters of Seogwipo.
