8Dubrovnik, Croatia: The Pearl of the Adriatic

Dubrovnik’s medieval walls, terracotta rooftops, and marble streets give it the air of a living museum. Often referred to as the “Pearl of the Adriatic,” this Croatian gem offers stunning views of the coast and a beautifully preserved Old Town that’s easy to explore on foot.

Fans of Game of Thrones will recognize many filming locations, but history buffs will be equally charmed by the city’s fortresses and ancient palaces.

Cruise tip: Walk the city walls early in the morning to avoid crowds and enjoy spectacular sea views.
