Welcome to 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.

Samui is about 228 square kilometres in size, measuring about 25 kilometres at its widest point. The most popular areas are located along the east coast.

The central part of Ko Samui is mostly tropical jungle with tree coverage and many beautiful creatures. It also includes its largest mountain, Khao Pom, peaking at 635 m (2,083 ft). The various lowland and coastal areas are connected by one route, which is a 51 km long road, encircling the island.
