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~
It's amazing! I highly recommend it! Whether you're diving or snorkeling, the scenery is breathtaking when the weather is nice. The fish aren't afraid of people, so you can see them very close. 👀 You absolutely must experience this when you come to Okinawa.
Thank you, Lin Jiang, for your patient instruction. You are very professional and reliable, and you are great at encouraging people who are afraid of water to keep trying. The location is very close to the bus stop, which is very convenient. If the weather is bad, the trip to Dream Reef will be changed, and it may not be possible to go to Green Cave. The diving experience is one instructor for two people, but snorkeling will be done in groups with other tourists. The on-site shower facilities are rather basic.
