Capri is pure romance—dramatic views, the bluest ocean you’ve ever seen, even the scent of lemon blossoms in the air. The luminescent Blue Grotto, striking Faraglioni Rocks and the Palazzo al Mare are popular with travelers, but for a real treat, snorkel at Marina Piccola beach. It’s said to be the spot where Odysseus nearly succumbed to the Sirens’ song… a fitting legend for this alluring island.

Pompeii is a Roman town frozen in time, thanks to a devastating eruption of Mount Vesuvius in 79 AD. Explore houses from modest to majestic; see Roman shops, baths and brothels; or apply your high-school Latin to the graffiti that's still visible on some of the walls. End your visit at the Villa of the Mysteries, and try to interpret its amazing, bizarre frescoes—scholars have debated their meaning for years.

Land of Mermaids. Land of Orange and Lemon Groves. Land of Colors. This small city in Campania has earned a plethora of alluring names. Famed for its sea cliffs, the town's steep slopes look out over azure waters to Ischia, Capri and the Bay of Naples. The birthplace of Limoncello liqueur offers some good diving, great sea fishing, boat cruises and appetizing restaurants. Excellent hiking trails cross the peninsula. Rent a car or take a taxi if the steep streets look too intimidating.

Serving as the main port town for the island of the same name, the town of Ischia has been inhabited for centuries, famous for its beaches and the healing waters of its spas. The town is divided in two: Ischia Porto is the harbor district and commercial center of the island, filled with brightly lit taverns and bars, and Ischia Ponte, the historic quarter, with its ancient castle and its stone streets seemingly frozen in time.

Once a vital part of a mighty sea power, Positano is today a sophisticated resort on the central Amalfi Coast. Moorish-style architecture rises up steep slopes that gaze out on the Sirenuse Islands. Smart boutiques, selling fashions for visitors to display on Grand Beach, abound in the village. And it’s a great base for exploring the area—you can easily travel by boat to Capri, Ischia and the Grotta dello Smeraldo cave.

Three miles of twisty mountain roads up from Amalfi, the gorgeous resort of Ravello has been attracting celebrities for centuries, including Richard Wagner, Greta Garbo, Gore Vidal and D.H. Lawrence, who wrote Lady Chatterley’s Lover here. Ravello’s Duomo (Cathedral) and Villa Cimbrone (both 11th century) and Villa Rufolo (13th century) are all magnificent sights. The annual summer Ravello Festival began as a salute to Wagner’s music, but now showcases a wide range of music and arts.

Stretching along the southern side of Italy's Sorrentine Peninsula, the Amalfi coast dazzles with its mysterious grottos, craggy cliffs and shimmering bays. Grab a seat on the sea side of a regional bus to soak up views on the fabled route from artsy Positano to Amalfi. Ravello offers some respite from the crowds, plus the stunning Villa Cimbrone, which overlooks the Bay of Salerno. The historic section of Sorrento has winding streets filled with craftspeople. Capri is only a hydrofoil or ferry ride away.

An area that changed flags several times in the 20th century, Eastern Poland consists of Podlaskie, Lublin and Subcarpathian Voivodships (Provinces). The largest cities in each are Bialystok, Lublin and Zamosc respectively. The Masurian Lake District in the northeast includes Wigry National Park and Lake Hancza, the deepest lake in Poland. Bialowieza National Park, on the Belarusian border, protects one of the last remaining sections of a huge primeval forest that once covered Eastern Europe.

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. 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.
