About Koh Samui
Ko Samui (เกาะสมุย), often called just Samui (สมุย) is an island of great natural beauty and variety in the Gulf of Thailand. The palm-fringed shoreline and coconut and fruit cultivation of the coastal lowlands rise to a central granite massif, the slopes of which are cloaked in virgin rainforest.
