Like Rothenburg, Dinkelsbuehl is one of the smaller mediaeval fortress cities. With its walls and towers still intact, it has the look of a typical German town of the 15th to early 17th century. Sample the famous German cuisine served in larger cities, but without the crowds. Don't miss the annual summer celebration, marking the city's surrender to Swedish troops during the Thirty Years' War. The event is emphatically reenacted by many of the town's residents. And really, who doesn't love amateur theatre?

Walk atop Rothenburg’s city walls or climb to the top of the town hall for great views. The Night Watchman tour is an unforgettable way to learn the city’s history. And our travelers also recommend the Medieval Crime Museum (Mittelalterliches Kriminalmuseum)—it’s gruesome but fascinating.

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.

Once a vital part of a mighty sea power, Positano is today a sophisticated resort on the central Amalfi Coast. Moorish-style architecture rises up steep slopes that gaze out on the Sirenuse Islands. Smart boutiques, selling fashions for visitors to display on Grand Beach, abound in the village. And it’s a great base for exploring the area—you can easily travel by boat to Capri, Ischia and the Grotta dello Smeraldo cave.

Cairo’s an ancient city that also happens to be a modern metropolis—it’s one of the biggest cities in the Middle East and has the traffic and noise issues to prove it. But as long as you’re not looking for solitude, Cairo—the City of the Thousand Minarets—is a splendid place to explore Egyptian history and culture. (Editor's note: Our list was compiled before political unrest prompted many countries to issue travel warnings for Egypt. If you're currently planning a trip to Egypt, please consider the risks and monitor your government's travel alerts.)
