In 1715, margrave Karl III Wilhelm decided he needed more space than he had in Durlach, so he moved his capital to Karlsruhe and had it designed in circular spokes around his new palace. Because of its unique radial shape, Karlsruhe is sometimes called the “fan city.” Home to Germany’s most important federal courts, the city accordingly teems with civil servants. Karlsruhe Schloss (castle) was badly damaged in World War II, but was rebuilt and is now home to the Badisches Landesmuseum.

Over 15 million gallons of water bubble daily into Budapest's 118 springs and boreholes. The city of spas offers an astounding array of baths, from the sparkling Gellert Baths to the vast 1913 neo-baroque Szechenyi Spa to Rudas Spa, a dramatic 16th-century Turkish pool with original Ottoman architecture. The "Queen of the Danube" is also steeped in history, culture and natural beauty. Get your camera ready for the Roman ruins of the Aquincum Museum, Heroes' Square and Statue Park, and the 300-foot dome of St. Stephen's Basilica.

Copenhagen is one of Europe’s oldest and most popular cities. It’s also one of the cleanest and most metropolitan. The dynamic Danish capital features progressive modern architecture, the must-visit Tivoli Gardens amusement park, stunning palaces, and all the activities and amenities you would expect in a world-class destination. Explore the canals and pretty narrow streets, appreciate beautiful old homes, and find great shopping and people watching on The Ströget.

Livingstone is more than just a pitstop for Victoria Falls—it's a destination in its own right. The town has an old-world charm that makes you feel like you've stepped back in time. Brush up on your Zambian history at the Livingstone Museum and grab some samosas from a street vendor for the full experience. And if you need some more adventure, it's never too far. Take a sunset cruise down the Zambezi River or go on a safari to learn about the natural wildlife and environment. Then there's Victoria Falls, of course, where you can choose to get soaked at the bottom or venture out to the edge of Devil's Pool.
