You push off a wooden pier as heat lifts from the sand and the sea opens ahead — limestone karsts rise like green-shouldered islands, currents nudging the hull toward a narrow slit in rock. That slit is Tham Morakot, the Emerald Cave on Koh Mook: a lung of ocean that, at low tide, admits a boat into a hidden lagoon where light turns the water a startling green.
