About this site
Sunken Island is a submerged plateau reef in the Hinoba-an area, presenting as an immersed, flat-topped structure that divers descend onto from above. The reef bottom reaches a maximum depth of 8 m, making it a shallow site but one with strong currents that demand respect.
The plateau hosts a diverse array of reef fish, with occasional sightings of green sea turtles and hawksbill turtles among the most notable encounters. Sea snakes are also present at this site.
Strong currents are the defining condition here and represent the primary hazard. Because of this, Sunken Island is recommended for experienced divers, and nitrox certification is specifically advised before diving it.
