Ryuodo Cave

Mysterious scenery in the Kotoura Caves

Just one among the rich variety of Kotoura caves, Ryuodo Cave is called "Sado's Blue Grotto," and is the largest lava rock cave on the island. Like the Blue Grotto in Italy, the sunlight creates a beautiful blue reflection and the waters glow brilliantly on days of mild weather and sea conditions. Sea kayak tours are available, providing participants with a chance to navigate into the cave and enjoy an otherworldly view.
