The speedboat cuts through warm Andaman water and, in fifteen minutes, the horizon tightens into three low islands—Koh Khai Nok, Nai and Nui. White sand glints; a guide points to a crown of coral off a rocky shelf while the sea murmurs and small fish dart between your toes. Morning trips arrive with glassy water and cooler light; afternoon runs bask in golden warmth.
