Palm-fringed beaches, turquoise Gulf of Thailand, and the wonder of Ang Thong's emerald lagoons.
Koh Samui is Thailand's second-largest island and one of Asia's most iconic island paradises. Palm-fringed beaches, turquoise water, luxury spas, and lively nightlife spots make it the most popular destination on the Gulf of Thailand coast. The Big Buddha temple and the stunning green lagoons of Ang Thong Marine National Park are the island's unmissable highlights.
