Unlike the Andaman Coast, Koh Samui and its sister islands (Koh Phangan and Koh Tao) sit sheltered inside the Lower Gulf of Thailand—making them Thailand's #1 sunny beach destination from May right through September. Samui pairs five-star hillside infinity villas and Bophut's wooden Chinese shophouses with immediate catamaran hops to Koh Tao's coral reefs.
