Continuing their voyage along Croatia’s coastline, the Shards leave Dubrovnik and sail north to the fortified town of Ston where they visit the treasured salt pans. In Mali Ston, they meet a local oysterman who takes them out in his boat where they help harvest the oysters his son prepares for dinner. Next they sail to the barren islands of Kornati Islands National Park where they’re caught in Croatia’s most dreaded type of storm - a bora. Then they sail north to the island of Dugi Otok where they dive for giant mussels.
