★Snorkel and explore the popular “Blue Cave” in northern Ishigaki.
As the name suggests, the water inside the cave is clear blue, and if the conditions are met, it shines even bluer reflecting the blue sky and the sun.
You can go ashore to explore the inside of the cave and see limestone formations shaped by nature over thousands of years.
After exploring the cave, it is time for snorkelling.
Then swim along a coral channel full of tropical fish and colourful corals.
You will be amazed at the clarity of the ocean!
★An eco-friendly tour designed with sustainability in mind, to protect Ishigaki's nature for future generations.
