Blue Cave Snorkeling from Onna: Boat Trip to Okinawa's Blue Cave
Select participants and date
You step from a shaded parking lot at Ryukyu Mura and the sea coughs up a briny breeze that smells like salt and rusted coral. After a quick transfer—ten minutes to the dive shop, five to the port—you’re on a boat that slices toward the Blue Cave, Cape Maeda’s famous aperture where sunlight filters through seawater and paints the limestone walls electric blue. The entry is intimate: a narrow mouth, a brief boat drift, then the world compresses into shafts of color and schools of fish that treat the cave like a cathedral.

Adventure Tips
Bring reef-safe sunscreen
Apply a biodegradable, reef-safe sunscreen before you arrive to protect coral and avoid reapplying in the water.
Wear the provided marine boots
Boots protect your feet on slippery boat decks and rocky entry points—mandatory and worth using for stability.
Morning departures yield better visibility
Choose an early time to minimize wind and get the clearest, bluest cave lighting for photos.
Know the health rules
If you have heart, respiratory, or spinal issues, or are pregnant, you will be refused for safety—check restrictions before booking.
