This snorkeling experience at Okinawa's Blue Cave was truly amazing! The all-Chinese service made us feel very safe and secure during the explanations and equipment setup; communication was seamless. Taking a boat not only saved energy but also made the process much easier. The mysterious blue light inside the cave was breathtaking, the water was crystal clear, and there were plenty of fish. The instructors were also very attentive and helpful. The entire itinerary was transparent, and there were no extra charges on the day. It's an excellent value option for beginners or families, and I highly recommend it!
We came to Okinawa for a family trip, and I signed up for the Blue Cave snorkeling tour because I thought elementary school children would love it. As expected, the kids loved it and said that it was the most fun moment of their Okinawa trip. It was their first time snorkeling, so I was a little nervous and worried at first because I couldn't speak Japanese, but the pretty and kind female guide spoke English very well, so we had no trouble communicating at all. We had a reservation for the 8 AM time slot in mid-February, so I was worried about the kids getting cold, but the weather was great, and once we put on our wetsuits, all those worries disappeared. Plus, the guide said that there weren't many people and the weather was nice right now, so we could go into the Blue Cave, which felt like a gift! The guide explained everything well, took beautiful pictures and videos, and even fed the fish, making it a special experience. I was so happy. Okinawa is a popular and famous place in Korea, but I definitely want to recommend the Blue Cave snorkeling with our guide to my friends!! And guide~ Please come to Korea again to see Twice's concert:)))) Thank you for giving our family a fun experience~
