The boat slips away from the harbor and the karst towers begin to appear like slow-rising islands, each one pushing up from the sea as the morning mist peels back. On deck, the wind trims the scent of salt and lemongrass; beyond the rail, small fishing boats chart a steady course through limestone needles that have stood for millennia.
