Paris
Everyone who visits Paris for the first time probably has the same punchlist of major attractions to hit: The Louvre, Notre Dame, The Eiffel Tower, etc. Just make sure you leave some time to wander the city’s grand boulevards and eat in as many cafes, bistros and brasseries as possible. And don’t forget the shopping—whether your tastes run to Louis Vuitton or Les Puces (the flea market), you can find it here.
London
The crown jewels, Buckingham Palace, Camden Market… In London, history collides with art, fashion, food, and good British ale. A perfect day is different for everyone: culture hounds should hit the Tate Modern and the Royal Opera House. Clotheshorses will drool over Oxford Street shops. For foodies, cream tea at Harrod’s or crispy fish from a proper chippy offers classic London flavor. Music and book buffs will freak out over Abbey Road and the Sherlock Holmes Museum (at 221B Baker Street, natch).
Italy
Florence
Florence is an art historian’s dream. The Galleria dell'Accademia bursts with works by Michelangelo, who is entombed within the frescoed walls of the Basilica di Santa Croce. Budding photographers can snap pics of the Ponte Vecchio bridge, and serious shoppers can spend a blissful afternoon wandering the shops of Piazza Santo Spirito. Tuscan cuisine pays homage to the region’s bounty. Swipe a hunk of crusty bread across a pool of local olive oil and you’ll be instantly transported to your happiest place.
Venice
With its gondolas, canals, amazing restaurants, and unforgettable romantic ambiance, Venice is definitely a city for one's bucket list. Waterfront palazzos, palaces, and churches make drifting down the Grand Canal feel like cruising through a painting. To really experience Venice you must go to the opera or to a classical music performance, nibble fresh pasta and pastries, and linger in the exhibit halls of an art gallery. Label lovers will drool over the high-end shopping in Piazza San Marco.
Rome
Rome can’t be toured in a day, either. The city feels like the exhibit halls of a giant outdoor museum, a real-life collage of piazzas, open-air markets, and mind-boggling historic sites. Toss a coin into the Trevi Fountain, drop your jaw at the Colosseum and the Pantheon, and fuel up on cappuccino for an afternoon of shopping at the Campo de’Fiori or Via Veneto. Dig into a plate of fresh pasta, some succulent fried artichokes, or a tender oxtail stew for one of the best meals of your life.
Barcelona
Barcelona feels a bit surreal – appropriate, since Salvador Dali spent time here and Spanish Catalan architect Antoni Gaudí designed several of the city’s buildings. Stepping into Gaudí’s Church of the Sacred Family is a bit like falling through the looking glass - a journey that you can continue with a visit to Park Güell. Sip sangria at a sidewalk café in Las Ramblas while watching flamboyant street performers, then create your own moveable feast by floating from tapas bar to tapas bar.
Prague
The bohemian allure and fairytale features of Prague make it a perfect destination for beach-weary vacationers who want to immerse themselves in culture. You could devote an entire day to exploring Prazsky hrad (Prague Castle), then refueling over a hearty dinner at a classic Czech tavern. Spend some time wandering the Old Town Square before heading over to gape at The Old Town Hall and Astronomical Clock. Prague’s best bars are found in cellars, where historic pubs set the scene for a night of traditional tippling.
Berlin
Berlin is an edgy city, from its fashion to its architecture to its charged political history. The Berlin Wall is a sobering reminder of the hyper-charged postwar atmosphere, and yet the graffiti art that now covers its remnants has become symbolic of social progress. Check out the Weltzeituhr (world time) Clock, topped by a model of the solar system, then turn back time by dining at the historic Zur Letzten Instanz, a 16th century restaurant that was frequented by Napoleon and Beethoven.
Istanbul
The mosques, bazaars, and Turkish baths of Istanbul could keep you happily occupied for your entire trip: an eyeful of breathtaking architecture here, a good-natured haggle over a carpet there. Kick your trip off at the awe-inspiring Sultan Ahmet Camii (Blue Mosque), which is visible from many points of the city. Stroll the Galata Bridge and stop by the Miniaturk Park to see its tiny artifacts. The Grand Bazaar has thousands of shops to browse, while the Egyptian Bazaar is a fragrant trove of spices and fruits.
St Petersburg Russia
The second largest city in Russia, St. Petersburg is the country’s cultural heart. View splendid architectural gems like the Winter Palace and the Kazan Cathedral, and give yourself plenty of time to browse the world-renowned art collection of the Hermitage. Sprawling across the Neva River delta, St. Petersburg offers enough art, nightlife, fine dining and cultural destinations for many repeat visits.
