Koh Samui Island in Thailand: Infrastructure Overview

Koh Samui is a unique place that has preserved its natural authenticity due to its geographical isolation from mainland Thailand. Located in the Gulf of Thailand, the island has a different rainy season, allowing visitors to enjoy pleasant weather during the summer months. Koh Samui is a combination of untouched tropical forests, blue beaches, and a well-developed residential infrastructure for tourism and permanent living.

The island covers an area of only about 230 square kilometres, with a permanent population of 68,000 people. It has an international airport with regular flights to mainland Thailand, as well as to Singapore, Kuala Lumpur, and Guangzhou. The administrative centre and capital of Koh Samui is the town of Nathon, located on the western part of the island. Koh Samui’s postal code is 84330.
