Medieval history meets breezy Mediterranean vibes in Dubrovnik, where towering stone fortresses rise from the sparkling Adriatic Sea. Walk along the ancient walls that surround Old Town to get a sweeping view of the city dotted with monasteries, palaces, and terracotta rooftops. Or, hit the beach: Most are pebbly and rugged, but if you’re looking for a stretch of sand, hop on a ferry and head to Lopud, a car-free island where you can kick back on Šunj beach, grab a bite in the village, or check out Lopud 1483—a restored 15th-century Franciscan monastery. There’s even more to do, and we’ve got recs below.
