Thổ Chu Island

Thổ Chu is the largest island of a small group in the Gulf of Thailand, southwest of the island of Phú Quốc and west of the Cà Mau peninsula. The group consists of eight islands, with Thổ Chu rising above its smaller neighbours. Its rocks are sedimentary, and the sea surrounding it opens toward both the Cambodian coast and the western shore of the Mekong Delta. The islands stand apart from the mainland's low, alluvial coast.
