Although getting lost caused us to be late, they still tried their best to wait for us. The tour guides were very helpful, and the weather was perfect that day, allowing us to see the beautiful Blue Grotto scenery.
The activity team will lead you to explore the beautiful ocean of Ishigaki Island and take you deep into the Blue Hole to admire the beauty of coral reef lava caves. It's an impressive experience and highly recommended.
Even though it was cloudy and rainy, we still went snorkeling and saw beautiful sea fish and the Blue Hole. It was a wonderful experience to feel one with nature. The staff were very nice.
It was super fun 🥰 All I had to do was go to the meeting place, and they would take a bus to pick me up, play with me, and take all the photos for me without me having to worry about my phone. After it was over, we even had a meal, so I had a really comfortable and enjoyable time without having to worry about anything 😆 The instructors were kind, and they even gave us bread to play with the fish and took care of everything, so I highly recommend it to anyone, unless you can't swim 👍💖
Our group consisted of 10 people, all of whom were Japanese except for us. There were instructors who could speak Chinese, but it was still helpful to know some English to communicate. There were two snorkeling spots, both of which required a short boat ride to reach. I recommend renting a wetsuit for sun protection and warmth. Although it was hot on the shore, the seawater was still quite cold, and you wouldn't be able to stand being in the sea for four hours. The water was very clear, and you could see a lot of coral reefs, fish, and sea turtles. We were also very lucky to encounter a sea snake. It was a fantastic experience, and I would definitely participate again next time!
