There are many tributaries of the Sarakata River in the jungles of Santo, the main river whose mouth is on the West end of the main town Luganville. One of these tributaries sinks into the karst and makes brief appearances on the surface no less than 7 times over the course of approximately 1km where it finally emerges at the Tourist Blue Hole. The system was discovered, explored & mapped by local divers and CDAA cavedivers between 1994 and 1997.
The Sarakata Resurgence has been listed on another page as it is a separate tributary.
