Overview
Koh Samui is Thailand's second-largest island -- a tropical paradise in the Gulf of Thailand known for its palm-fringed beaches, coconut groves, and lush mountainous interior. From the lively shores of Chaweng to the tranquil bays of Bophut and Lamai, the island offers a refined Thai island experience.
For points travelers, Koh Samui is anchored by the stunning Conrad Koh Samui, a Hilton portfolio standout that sits on a private hilltop overlooking the Gulf of Thailand. Marriott and IHG also have a growing presence on the island.
Beyond the resorts, Koh Samui offers a rich mix of Thai culture, wellness, and adventure. Visit the iconic Big Buddha temple, explore the night markets of Fisherman's Village, or island-hop to the stunning Ang Thong National Marine Park.
Best Time to Visit
Dec - Apr (Recommended)
The dry season from December to April is the best time to visit with sunny skies and calm seas. Unlike the Andaman coast (Phuket), Koh Samui's Gulf of Thailand location means the wettest months are October and November. May through September is a pleasant shoulder season with fewer crowds.
