Since we went in February, the one-day tour was only a half-day tour due to the cold water temperature. They taught us carefully even though it was our first diving experience. We even saw a whale from the boat on the way. I dropped my underwater camera, but they found it at the same point the next day. Thank you very much.

There was a shuttle service from the port, which was helpful. The diving experience started at 13:00, so there was no time before or after, but there was a beach, an observation deck, and a place where ice cream is sold nearby. If you want to spend time in the ocean, you need to bring a leisure sheet. It was colder than I expected on the boat and in the ocean in February, but I enjoyed it very much. After diving, we had time for snorkeling. We were able to see sea turtles on the boat back to the facility.
