If you fancy an adults-only day out by the sea, Portopiccolo (half an hour’s drive) has a shingle strip with a lido and swimming pool, plus a pretty marina to potter around and lots of waterfront bars to while away leisurely evenings. You can also taste wines produced at vineyards near the campsite, or enjoy regional specialities like prosciutto and dumplings at simple 'osmica' restaurants. Kids in tow? Let them burn off energy on hikes, bike rides or pony trekking through rugged Karst Plateau landscapes, or join them for a day messing about on the treetop rope courses and zipwires at Trieste Adventure Park. Mix a bit of history into your family adventures by hiking the clifftop Rilke Trail (half an hour) past limestone caves used as bunkers and hideouts in World War II to 14th-century Duino Castle (25 minutes), which is open for tours of antique-filled apartments. And after all that, spoil them with a trip to the beach at Sistiana (half an hour) with play areas, sun lounger hire and watersports including snorkelling and boat hire.
