We had such a fun time snorkeling!
The tour was great, and the staff were so friendly and fun.
We even got to see sea turtles, which made us really happy.
The atmosphere was relaxed, and we felt comfortable the whole time. We’d love to come back.

The three of us joined a snorkeling and kayaking tour in early January.
It was our first visit to Kerama, and I was a little worried about snorkeling with our 7-year-old. But the water was so clear we could see the bottom, and the colorful fish made it a wonderful experience.
We’re very grateful to all the staff.

This was my second time trying scuba diving. On my previous dive, I’d had trouble breathing and felt really scared, so I was nervous.
But the staff explained everything patiently. I could breathe comfortably and really enjoyed the dive.
I’d love to dive with Okinawa Aquamarine again!
