Blue Cave Introductory Diving
Tour Details
Tour Details
The Blue Cave is Okinawa's most popular spot for diving. Beyond the mysterious blue glow inside the cave, the area is rich in tropical fish and coral, making it a perfect first-time diving point in Okinawa.
At B-nature, fish feeding is included in the price. Getting up close with the fish is an unforgettable experience — not just for adults, but for kids too.
You don't need any diving certification or prior skill — beginners are welcome.
By meeting directly at the site, the tour itself is shorter, leaving you more time to enjoy!
