Before the trip, I checked the weather forecast and it said it was going to rain, so I didn't make a reservation in advance, but I checked the weather at the destination and made a reservation the day before. I made a reservation because I could make a reservation on the day I wanted at a good price, and it was the best choice :) I can communicate in Japanese and English, and although I can't speak Korean fluently, there was no problem with the experience! Taku, who guided me, was very kind, and my husband, who was afraid of water, had a great time overcoming his fear😊 Above all, I could feel that they were trying very hard to help me meet sea turtles. Thanks to them, I was able to meet sea turtles at the end and take pictures and videos! It was such a fun and satisfying experience 🤩 Don't hesitate and definitely sign up for snorkeling! You'll make memories that are better than you expected :D
