Amphoe Ko Samui

Amphoe Ko Samui sits on the island of Koh Samui in the Gulf of Thailand, within Surat Thani province. The region’s diving character is tied to the Gulf of Thailand’s warm, calm waters, with accessible shore dives and short boat trips from Ko Samui’s beaches and villages. While this area is more known for its white-sand beaches and snorkeling, reliable conditions typically yield clear visibility in tropical depths along coral patches, sandy bottoms, and offshore islets. Divers visiting the region should expect gentle current regimes and a range of small tropical reef dwellers, with occasional larger pelagics farther offshore. The concentration of dive centers around Ko Samui aids practical access to charter trips, with many operations offering beginner-friendly experiences and guided reef explorations near shallow fringing reefs and nearby islets.
