Dubrovnik is a living fairy tale that shouldn't be missed. It feels like a small town today, but 500 years ago, Dubrovnik was a major maritime power, with the third-biggest navy in the Mediterranean. Still jutting confidently into the sea and ringed by thick medieval walls, Dubrovnik deserves its nickname: the Pearl of the Adriatic. Within the ramparts, the traffic-free Old Town is a fun jumble of steep alleys, low-impact museums; al fresco cafes, and kid-friendly squares. After all these centuries, the buildings still hint at old-time wealth, and the central promenade remains the place to see and be seen.
