In Vienna, the coffee house isn’t just a hangout: it’s an institution. Lingering over a newspaper with a pastry and a strong espresso drink is, according to UNESCO, officially a Viennese cultural pastime. Walk off your slice of Sachertorte with a self-guided tour of the city’s stunning traditional, Secessionist, and modern architecture, such as the Imperial Palace, the State Opera House, the Kirche am Steinhof, or the Kunsthistorisches Museum, an exercise in ornate geometry.

Rome wasn't built in a day--and you'll need much more than a day to take in this timeless city. The city is a real-life collage of piazzas, open-air markets, and astonishing historic sites. Toss a coin into the Trevi Fountain, contemplate the Colosseum and the Pantheon, and sample a perfect espresso or gelato before spending an afternoon shopping at the Campo de’Fiori or Via Veneto. Enjoy some of the most memorable meals of your life here, too, from fresh pasta to succulent fried artichokes or a tender oxtail stew.

Amsterdam is truly a biker’s city, although pedaling along the labyrinthine streets can get a little chaotic. Stick to walking and you won’t be disappointed.

The Anne Frank House is one of the most moving experiences a traveller can have, and the Van Gogh Museum boasts a sensational collection of works.

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.
