South Natuna
South Natuna is an archipelago off the west coast of the island of Borneo, the southernmost group of the Natuna Islands in the South China Sea. Geographically it is part of the Tudjuh Archipelago, and administratively part of the Riau Islands province of Indonesia.
The archipelago is spread out over hundreds of kilometers. Major islands include Greater Subi Island, Lesser Subi Island, Bakau, Panjang and Serasan. The Api Passage separates the South Natuna group from the island of Borneo. The Selasan Strait cuts through the bottom of the cluster of islands.
