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.

Once known for smog, traffic and tacky architecture, Athens is a city reformed thanks to fortunes brought by the 2004 Summer Olympics. Spotless parks and streets, an ultra-modern subway, new freeways, an accessible airport and all signs in perfect English make the city easily negotiable. Meriting more than a stopover en route to the islands, sophisticated Athens sites include many pillars of Western history, from the Acropolis to the Temple of Olympian Zeus, as well as treasures in the National Archaeological Museum.

This city, full of colorful homes, canals and bridges, is one of Europe's most picturesque capitals.

For an unusual and memorable alternative to hotels, consider staying in a houseboat.

Lingering over pain au chocolat in a sidewalk café, relaxing after a day of strolling along the Seine and marveling at icons like the Eiffel Tower and the Arc de Triomphe… the perfect Paris experience combines leisure and liveliness with enough time to savor both an exquisite meal and exhibits at the Louvre.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same.

Traditional attitudes prevail in the historic Sinai region on Egypt's border with Israel. The triangular peninsula is divided from the rest of Egypt by the Suez Canal and the Red Sea.

Spectacular snorkeling and diving sites beckon from the Gulf of Aqaba to the east of the peninsula, particularly along the dramatic coastline of Na'ama Bay in Sharm el Sheikh. Camelback safaris offer distinctive desert excursions.

La Palma is a pristine paradise, set against a backdrop of volcanic landscape. Perhaps the best way to experience La Palma’s rugged beauty is a hike through the Caldera de Taburiente National Park or the narrow gorges of Los Tilos. The cool waters of natural swimming hole Charco Azul beckon on a steamy day. The dark sands of Playa Nueva are great for sunbathing and cat naps.

The valley of Kashmir is as rich with history and political controversy as it is with culture and natural phenomena.

Of course, native craftsmanship makes for excellent souvenirs—carpets and textiles are an especial shopping must.

Montreal, c’est si bon! This French-speaking city is considered the cultural capital of Canada, and is a cosmopolitan celebration of Québécois style. A horse-drawn carriage ride around the cobblestone streets and grand buildings of Vieux-Montréal will give you a taste of European flavor. The Basilique Notre-Dame is a confection of stained glass, and the Plateau Mont-Royal district will delight you with its quaint boutiques and cafés. Dig in to a massive plate of poutine to fuel up for a tour of the epic Olympic Park.

Conquering New York in one visit is impossible. Instead, hit the must-sees – the Empire State Building, the Statue of Liberty, Central Park, the Metropolitan Museum of Art – and then explore off the beaten path with visits to The Cloisters or one of the city’s libraries. Indulge in the bohemian shops of the West Village or the fine dining of the Upper West Side. The bustling marketplace inside of Grand Central Station gives you a literal taste of the best the city has to offer.
