📍 Destination Overview
Koh Samui is a resort island in the Gulf of Thailand, famed for its coconut-fringed white-sand beaches. Chaweng and Lamai are the liveliest beaches, while Bophut is tranquil and pretty. The island has the golden Big Buddha Temple, the curious Hin Ta Hin Yai (Grandfather & Grandmother) rocks, and from here you can reach the Emerald Lagoon of Ang Thong National Marine Park, or hop to Tao and Nang Yuan islands for snorkeling and diving. With its monsoon opposite to the Andaman, Samui's dry season centers in the middle of the year — a great off-peak island choice.
