The morning hum of the speedboat cuts through a glassy Gulf as limestone cliffs rear up like dark sculptures, daring you closer. Within an hour you’re threading between jagged islets, the engine easing while snorkel masks glint and paddles tap against blue. At Mae Ko’s viewpoint, wind pushes at your back and the park’s 42 islands spread in green and gray—pools of emerald water trapped inside calderas, caves with lotus-shaped formations, and beaches that hold only footprints for a day.
