Morning light slices across the Andaman as a speedboat cleaves the glassy water, carrying day-trippers toward a scatter of granite islands that dare you to look away. By the time the engine hushes, white sand and turquoise bays frame a shoreline carved by wind and time; palms gesture from pockets of shade while currents nudge you into coral gardens.
