More ways to explore the area's outdoor wonders
You step off the pier in Khao Lak before sunrise and the speedboat slices toward a horizon the color of polished aquamarine. Within an hour the island boulders loom — smooth, granite shapes rising from the sea — and the boat hums into anchor at a sheltered bay. Onboard MV KOON1, the engine’s steady whisper becomes background to the reef’s louder conversation: currents nudging you along coral gardens, tiny fish threading fan corals, and nightfall drawing out creatures that hide by day.
