Ko Samui and Ko Pha Ngan are neighbouring islands lying in the Gulf of Thailand off the east coast of the Kra Isthmus. They belong to the Samui archipelago. Ko Pha Ngan is the northernmost island of the pair with Ko Samui located 15km to the south. A portion of the mainland occupies the bottom left corner of this chart. To the west of the two main islands are the Mu Ko Ang Thong group of 42 small islands that run in a north-south line and form a marine national park.

Ko Samui is Thailand’s second largest island after Phuket and is a thriving tourist island. On the west coast is the island capital Nathon. From here, Ko Pha Ngan is easily accessible by ferry. Most of the population live by the coast as the island’s interior is very mountainous and largely inaccessible. Tourism is a growing industry here but on a much smaller scale than that of its neighbour.
