Often overlooked in favor of Porto and Lisbon, Coimbra sits on the banks of the winding Mondego River. After a day spent among the city's medieval architecture and grand university buildings, it's easy to see why Coimbra was Portugal's capital for over a century.

Nestled at the foot of the Black Forest in South Germany, Baden-Baden is a chic destination for those who fancy a dip in its famous salt- and radon-rich thermal hot springs. The town has been a popular destination for so long that it's starting to show its age, but not to worry. It's still very classy, picturesque and well-maintained. (The Dame Julie Andrews of German spa towns, if you will.) Sporty types will find an abundance of opportunities to enjoy golf, tennis, horseback riding and skiing nearby in winter.

Silky beaches, coconut palms, and designer boutique hotels are mainstays of Trancoso's casual chic vibe. Candy-colored clay houses line the streets and squares, lending a bohemian vibe to this otherwise rustic destination. The world-famous beaches boast velvety white sands and natural pools created by coral reefs.

Laid out by British architect Edwin Lutyens, the Indian capital is a striking modern metropolis. A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.
