One of the most popular resort towns on the Italian Riviera, little Portofino has just over 500 permanent residents. But that all changes on summer days when the sun is shining and the yachting set drops anchor in the harbor to wander about. Boutiques, art galleries, cafes and restaurants line the tiny streets. Diving, hiking and beach-going are popular local pastimes, and there are even some historic sights like the Church of St. Martin (Divo Martino) and the Castello Brown hilltop fortress.

Most visitors to Fiumicino arrive by plane and immediately continue on to Rome, but—in addition to being home to Italy’s busiest airport—the coastal town doubles as a beach resort during the summer months. There’s also Ostia Antica archaeological site, which is just a short drive away.

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. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.

This former Bedouin fishing village is now a popular tourist destination—especially for serious windsurfers, who'll find some of the best conditions in the world off Dahab's beaches. Long known as a laid-back, backpacker-friendly town, Dahab is becoming more developed, yet retains a casual vibe. Finally, Dahab is also home to the Blue Hole, the world's most dangerous dive site. Only very experienced technical divers should attempt passage through "The Arch" here; if you're a novice diver, stay close to the surface. (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.)

Walk the Freedom Trail the first time you visit Boston and you'll quickly get a sense of this coastal city's revolutionary spirit and history. But make sure you also explore some of Boston's fine museums (try the Isabella Stewart Gardner, featuring masterpieces displayed in their collector's mansion) and old neighborhoods (like the North End, Boston's Little Italy). You can't claim to have experienced real Boston culture, though, until you've watched a Red Sox game from the bleachers.
