Most of the islands consists of limestone mountains about 10-400 meters above sea level. Because the limestone can change its structure easily by both chemical condition and weather, so that makes the islands have many, strange-looking caves and cliffs, and some islands are looked like ancient Angkor Wat in Cambodia and Prasart Hin Pimai. You will feel the nature at your surroundings. Just go for it.
