The day before, the instructor will contact you to see if it is feasible based on the sea conditions. If it is not feasible, they will provide alternative solutions or cancel the trip. This time, we will change to snorkeling in Osaki and then snorkeling in Ishigaki Island in January. It will not be too cold, but you must keep warm when you come ashore!
The 660-meter length is worth seeing. The ticket price is over 200 yuan. Although the time is not very long, it takes about half an hour with stops along the way. Of course, it would be better if it were cheaper, but the overall experience is good.
I was wondering how to spend my day before returning home and came across the Blue Cave snorkeling program. It was rainy and windy throughout the trip, so I was worried it might be canceled. As expected, I was told the weather was bad and it wouldn't be possible to visit the Blue Cave site. Instead, they offered me two alternative locations and offered to help me with my snorkeling experience. I snorkeled at Osaki Beach Point. Considering the weather, it was definitely the perfect spot! My guide, Makoto, was especially cheerful and guided me. Despite the bad weather, he worked incredibly hard to ensure I had the best time :) Thanks to him, I had a truly safe and enjoyable snorkeling experience. Oh, and they even take plenty of photos during the experience. If you're visiting with family, friends, or a significant other, they'll take photos for you and send them to you via a convenient method. Don't worry, definitely try it! It was a great experience!
