Snorkel in the clear waters of the Blue Cave, located in the northern part of Ishigaki Island. Explore the cave and observe the natural products of Ishigaki such as limestone caves. Swim in the trench where many beautiful fishes and corals are waiting for you.

Be picked up from your hotel (only Southern Area) or Red Mail Post at Euglena Ishigaki Ferry Terminal and head to the Blue Cave. 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. Go ashore to explore the inside of the cave and observe the natural products of Ishigaki, such as limestone caves.

After exploring the cave, it is time for snorkeling. Swim in the trench where many beautiful fishes and corals are waiting for you. You will be amazed at the clarity of the ocean. If you are lucky, you may even see sea turtles.
