A short speedboat cuts through Andaman glass, flinging spray that smells of salt and diesel as it races east from Phuket toward three small islands—Khai Nai, Khai Nok and Khai Nui. Within 20–25 minutes the mainland blurs and a white arc of sand appears; water so clear you can track a fish before you dive.

Conservation
These islands rely on healthy nearshore reefs—use reef-safe sunscreen, avoid standing on corals and follow guide instructions to reduce damage to fragile marine life.
