Kerama Islands Snorkel.
A fast boat across open water to the clearest blue in Okinawa. Sea turtles, coral, and the bluest oceans in Okinawa.
A small charter boat takes you out to the Keramas, run by a local crew we've worked with for years. They find the calm water; you slip in — over coral, beside turtles, with no crowds.

The day.
- 8:00
Meet & board
the crew runs a quick safety briefing and gear fitting, and you cast off as a group.
- 30 minutes
Crossing
Open water from the coast to the islands. Spray, horizon, and the colour shifting under the hull as the depth drops away.
- 8:40
Snorkel stops
The boat anchors over coral, and you slip in. The boat will move rounf a couple of spots depending on the group and conditions.
- 12:00
Return to port
Back across the water to the port where you started.
The blue out here is real. Locals call it Kerama Blue, and once you've seen it you understand why it needed a name of its own. The visibility runs deep, the coral is healthy, and the whole island group sits far enough offshore that the water stays clear and the days stay quiet.
The boat is small — ten people, often fewer. The crew know this water: not shouting over a crowd, but pointing out a turtle before it drifts off, moving the boat when a better patch of reef opens up. Beginners do fine — everyone gets a wetsuit and flotation.
What you'll remember is the turtles. They feed in the shallows and they're in no hurry, which means you can float above one for a long while before it decides to move on. Coral underneath, sunlight cutting through, a turtle below you — that's the morning. The full day just gives you more of it.
“We did the full day and I'd do it again tomorrow. Calm boat, tiny group, and we swam with three turtles before lunch. The guide put us on the best water every single time. The blue out there doesn't look real.”

Full payment due at booking to secure your boat.
Full refund 48 hours prior. No refund less than 48 hours before the tour. Full refund if the captain cancels for unsafe sea conditions and the boat doesn't depart.
The crew who take you out have been working this water far longer than we've been sending guests to them — and they're the reason we keep coming back. We pick the people; they read the sea. Come ready to float, and leave the rest to us..

We did the 3 day 2 night tour and it was outstanding. The itinerary was so well thought out and we were well prepared for our trip. David was ready to answer any questions we had which we really appreciated. The activities were well planned but also we felt we had plenty time to relax and take in the surroundings. This is a trip that you absolutely need to add to your bucket list. We will be back hopefully!!
Aya was so sweet and informative during our Izakaya hopping tour. She made sure everyone felt comfortable with the dishes that were curated and was sure to dive deep into the culture, history, and background of Okinawa. We hope to come back again. Would definitely recommend!
Culture & Coast half day tour with. I was visiting from Australia and my tour guide was Aya. Visited market arcade stroll. Fresh fish and meat markets. Got to enjoy selecting a fish and how u like it cooked. Underground wartime tunnels & Memorial. South coast historic waterfall and tide pool. It was an amazing tour. Aya was awaresome with information about each place we visited. If your in Okinawa and want to explore and also visit the other islands around Okinawa highly recommend. I will be heading back to okinawa next year and will be booking with this tour again. 😀
