Reviews: 2-hour diving and snorkeling experience at the blue cave in Okinawa city, Japan [blue cave snorkeling/diving/English and Japanese instructors/shore entry to avoid seasickness]

Guest User2026-04-30

Everything was well organized. I was alone with the instructor. Since this wasn't my first dive, I enjoyed the clear water and the view of the cave's depths without worrying about whether I was doing everything correctly. Special thanks to the instructor for not bothering me too much, knowing my experience.

The activity was fun and I got to meet new people. The staff were responsible, capable, and even helped with photography. Also, the transportation from the hotel to the activity venue and back was very convenient.
