History

Koh Samui, one of Thailand’s most beloved islands, has a history as rich as its natural beauty. For centuries, it was a quiet fishing and coconut-farming community, with records of Chinese sailors and traders visiting the island as early as the 15th century. Its name is believed to derive from either the Malay word “saboey,” meaning safe haven, or the local name of a tree, both reflecting its importance as a stopover point for seafarers.

For much of its history, Koh Samui remained isolated due to its location and dense jungle interior. Villagers relied on boats for transport and trade, with coconuts becoming a primary export. The island’s secluded charm began to attract adventurous backpackers in the 1970s, drawn by its unspoiled beaches and laid-back atmosphere. With limited infrastructure, travelers arrived via small ferries and stayed in rustic huts, experiencing the island’s raw, untouched beauty.

By the 1990s, Koh Samui had evolved into a global tourist hotspot, with modern resorts and an airport connecting it to the world. Despite its transformation, the island retains its cultural identity, with vibrant temples, traditional markets, and local festivals offering a glimpse into its past, blending heritage with contemporary appeal.
