Blue Cave
Maeda, Onna Village
The Blue Cave has been one of the most popular diving spots on island in recent years. The place offers the extraordinary sight of the entire cave naturally illuminated in blue. The sunlight streaming in from the entrance hits the bottom of the cave through clear seawater, and the reflected light from the water provides a natural illumination to make the cave blue. The cave is located at the base of Cape Maeda, and unaccompanied swimming is dangerous. Most visitors go on a tour guided by a local diving shop or are accompanied by a local guide with knowledge of the geography of the area. Half of the cave is under water, so you must snorkel to enter it.
