1. The shuttle bus ride from Naha city center to the snorkeling shop was very comfortable; the bus was clean and had plenty of seats. 2. The staff and instructors at the snorkeling shop were very friendly and attentive to all group members. The instructors were fluent in Japanese, Chinese, and English, and their instructions were clear and reassuring. 3. The snorkeling trip, though short, was very rewarding. We saw many tropical fish, had a feeding session, saw the beautiful Blue Cave, and had some free time to swim. 4. The showers and changing areas were open-plan. The hairdryers were quite good and had strong airflow. 5. At the end, we received Okinawa noodle food vouchers, which could be redeemed at the noodle shop next door; the noodles were quite delicious. 6. The lockers were only suitable for valuables like phones and wallets; other bags could be placed in the open lockers. 7. Both the outbound and return buses stopped at American Village, so we got off there on our return trip to have dinner and watch the fireworks before taking the 8:15 PM last shuttle bus back to Kokusai-dori, which was very convenient.
The meeting point is in the parking lot. After finding your designated vehicle and reporting in, you'll fill out a declaration form, then change clothes and walk to the shore. You'll be provided with a mask (prescription is available for those with nearsightedness), snorkel, wetsuit, life jacket, and fins. The Japanese instructors can provide basic English instruction. After learning to breathe through the snorkel, you'll first experience snorkeling in the nearby waters before heading to the Blue Cave. Although the Blue Cave is well-known, it's often crowded, making the experience less enjoyable. While snorkeling, we saw many colorful tropical fish, and the instructors provided fish food to attract more. The instructors were very patient throughout, constantly taking photos and videos, which were then sent to us via mobile phone after the experience. The entire trip, from check-in to finish, took about 2 hours. Overall, highly recommended! Even those of us who can't swim had a great time!
The instructor provided timely guidance and reminders, and we also saw the beautiful Blue Cave. I hope to experience diving again next time! The paid video was definitely worth buying; it allowed us to savor the experience!
The pre-event preparations were thorough, with clear explanations and pictures. The staff were friendly and patient, and went out of their way to film the entire experience. Our family was very grateful to every staff member at Adventure Island. Free parking was provided (the staff at the information desk will tell you which parking space to park in upon arrival). There were lockers for valuables and hot and cold shower facilities with ample water pressure. The process was simple: after changing into your gear, it was just a 5-minute walk across the road to the pier to board the boat. A brief explanation followed, and the boat took about 10 minutes to reach the waters outside the Blue Cave. Overall, it's highly recommended. A great experience, especially suitable for students and families with young children.
Everything was so much fun, but it was a pity there were too many people snorkeling in the Blue Hole; all you could see when you looked up were feet. But the instructors were great!
