Koh Samui

Thailand's second-largest island, Koh Samui charms visitors with white-sand beaches, coconut palms and a jungle-covered mountainous interior. Between beach relaxation, golden temples and excursions to nearby islands, it offers a slice of tropical Thailand at its own pace.

Why visit Koh Samui?

Koh Samui is known for its white-sand beaches, turquoise waters and a drier climate than the rest of southern Thailand. The island combines well-developed tourist infrastructure, iconic Buddhist temples and easy access to neighbouring archipelagos in the Gulf of Thailand.

What to discover in Koh Samui?

Koh Samui owes its enduring reputation to palm-lined beaches, starting with Chaweng and Lamai, the island's two liveliest and most visited beach resorts, both lined with hotels and restaurants. Beyond the coastline, the island's interior reveals a mountainous jungle crossed by waterfalls, such as Na Muang, and winding roads offering views over the coast and the island's coconut plantations. Travellers seeking quieter beaches tend to head north instead, towards Bophut or Maenam.
The island also holds a notable spiritual heritage, with several remarkable Buddhist temples, including the golden Big Buddha overlooking the northeast coast. Nathon, the main town, retains the relaxed atmosphere of a fishing port and remains the island's administrative heart. Koh Samui also serves as an ideal gateway to the nearby islands of Koh Phangan and Koh Tao, as well as the Ang Thong marine park, all of which are reachable by boat for a full day trip.
