The sun lifts from the Adriatic and the boat slips out of Dubrovnik’s harbor, engines a steady hum beneath conversations and the scent of salt. Within an hour the shoreline thins and islands tumble into view: Lopud’s low hills, Mljet’s pine rim, and the bright mouth of a sea cave that turns the water an impossible blue. You spend the day hopping between swims, cliff-top viewing, and shaded walks beneath pines — a compact introduction to southern Dalmatia’s coastal geology and coastal life.
