An Overview of the Blue Cave Boat Diving Tour

This tour is crafted to minimize the typical barriers that scare off new divers or non-swimmers. Instead of a strenuous beach entry and heavy equipment carried down stairs, you’ll enjoy a smooth boat ride straight to the Blue Cave. It’s ideal for those who prefer a leisurely, comfortable experience without sacrificing the magic of Okinawa’s underwater wonder.

Being on a boat also means you’re less affected by weather and sea conditions—a significant advantage in the unpredictable Okinawan seas. The tour usually lasts around 2 hours, with boat rides totaling about 20 minutes (10 minutes each way), giving plenty of time for the main event: the underwater exploration in the Blue Cave.

The tour starts at the conveniently located 159-4 Maeganeku in Onna Village, a spot well-known among locals and travelers alike. From there, it’s a quick safety briefing, a speedy boat ride, and then your time exploring underwater. The guides—who speak both English and Japanese—are praised for their patience, careful instructions, and ability to make beginners feel at ease.

What Makes This Tour Stand Out?

Beginner-Friendly Approach

The tour is explicitly designed to be accessible for those new to diving or even non-swimmers. Guides provide detailed, step-by-step instructions, ensuring everyone feels comfortable before entering the water. Many reviews mention how helpful and reassuring the staff are, with some highlighting that even first-timers felt confident enough to enjoy the experience without prior training.

Small, Dedicated Groups

With a maximum of three participants per guide, you’ll likely receive personalized attention. This small-group setup is a noticeable advantage, allowing guides to tailor their support to your pace and comfort level. It also means less waiting and more hands-on assistance, which is crucial for beginners.
