Belgrade's long and storied history is suggested by its architecture, which varies from Byzantine and Ottoman to neoclassic and romantic buildings in the older neighborhoods, and from Art Nouveau to brutalism and neo-Byzantine design in New Belgrade. The city's many theaters, museums, monuments and opera houses boast a deep and fissured cultural life while the beaches and rivers attract sunbathers, sports enthusiasts and partygoers on the popular floating river barges that serve as nightclubs.

Charming Timisoara is often referred to as “Little Vienna,” and indeed, Austrian influences are evident in the architecture, food and culture. This is a walking city, divided into squares that showcase stunning architectural gems. Downtown is reserved for pedestrians only, and the best time to visit is at twilight, when you can sip a hot wine as you stroll amid sparkling lights.

St. Brelade, in the Jersey Islands, is home to several beautiful bays with golden sands. St. Brelade Bay is a great place for an active beach day—beachgoers enjoy canoeing, banana boat rides, trampolines and kayaking. Visit the Fisherman’s Chapel to see the perquage, a path from the chapel to the sea. Ancient law allowed a criminal to seek sanctuary in the chapel for eight days. On the ninth, he had to surrender or walk down the path to board a boat, which would carry him into permanent exile from the island.

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.

Conquering New York in one visit is impossible.

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.
