Dubrovnik

Dubrovnik is a great walking city for lovers of culture and history, with centuries-old monasteries, churches, synagogues and even one of the oldest operating pharmacies in Europe. But, if you're looking for a day of relaxation between busy tours in marquee cities, it's also a gorgeous spot to simply sit and watch the world go by amid red-roofed stone buildings and the sparkling, aqua Adriatic Sea.

The medieval-era Old Town is a walled city, and from above -- you can walk the 1.3-mile stretch some 80 feet above ground level for spectacular views -- it is reminiscent of Venice, just on a smaller scale (and with marble alleyways instead of canals). Like the Italian city, which lies just to the northwest, Old Town Dubrovnik is free of vehicular traffic and dotted with Renaissance churches and fountains, with a rich history as a trading port. In lieu of canals, you'll find narrow, cobblestone streets where pedestrians stroll from shop to shop, dine and drink at alfresco cafes and soak up the sun.

Dubrovnik is nestled in the southwestern corner of Croatia, a boomerang-shaped country directly across the Adriatic Sea from Italy's east coast, under which lies Bosnia and Herzegovina. The atmosphere is light and welcoming, due in no small part to the city's gorgeous setting on the Dalmatian Coast, which can be appreciated on one of the many boat tours offered from the Old Town harbour. Nearby beaches are also accessible; tours further inland include country bike rides and wine-tasting.

The port is a mainstay on Eastern Mediterranean cruise itineraries, sprinkled among greatest-hits stops like Athens, Venice and so many Greek Isles. Most Eastern Mediterranean cruises set sail from spring through fall, though winter cruising is gaining popularity.
