Consists of numerous islands with high and steep granite mountain, beaches and rocks formation of many shapes. The shoreline of each islands are of inconsistent curves since they are situated in the outer part of the sea and are worn away directly by waves. Part of the water lies in the Andaman Sea and eastern side of the Indian Ocean while the shoulder of the continent borders the western shoreline of Phang Nga province and Union of Myanmar, paralleling the Nikobar Islands of India. There is no mud at all along the beaches, so the sands are very clean, white and very fine. Some islands do have hills in the area, which are usually quite tall with the highest top of 244 meters above mean sea level, while some islands are of flat area surrounded by sand dunes and coral reefs.
