Koh Samui is in the gulf of thailand which surround by land of Thailand in north, Cambodia and Vietnam in east and Malasia in south. The sea around Koh Samui connect to South China Sea and Sulu Sea.
Koh Samui is surrounded by about sixty other islands, which compose the Ang Thong Marine National Park (Mu Ko Ang Thong National Park) and include other tourist destinations (Ko Samui, Ko Phangan Hotel, Ko Tao Hotel and Ko Nang Yuan).
It remains the major port for fishing and inter-island transportation. Nathon is the seat of the regional government, and the true commercial hub of the Samui locals. It has a charming pace, and is almost small enough to walk everywhere. The old Chinese shop houses along the middle street whisper of an exotic history.
