Lying at Italy’s geographic and historic heart, Lazio (or Latium) was the seat of the Roman Empire, and as such is teeming with ancient attractions, especially in the Eternal City of Rome itself. To the east, Tivoli has Emperor Hadrian’s exquisite and massive Villa Adriana. Civitavecchia, today a major cruise and ferry port, has been Rome’s main harbor since the second century. Many pre-Roman sites dot Lazio too, like the Etruscan necropolis at Cerveteri, dating from the 9th century BC.

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.

Olbia (Greek for “happiness”) is a popular jumping-off point for those visiting the white-sand beaches of the Costa Smeralda, but those who linger in the coastal city uncover a historic centre filled with archaeological landmarks, piazzas ringed by wine bars, and authentic eateries.

Famed for winter skiing and summer hiking and climbing opportunities, the Dolomites are a section of the Alps in northeastern Italy, running roughly from Pieve di Cadore in the east to the Adige River in the west. Marmolada, just east of Trento, is the highest peak, at nearly 11,000 feet. The dramatic and craggy mountains are famed for their unique colors, which are the result of their partial formations as undersea coral colonies before being pushed upward millions of years ago.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment. Catch a show at the Dubai Opera, see downtown from atop the Burj Khalifa and spend an afternoon along Dubai Creek exploring the gold, textile and spice souks. If you’re looking for thrills, you can float above the desert dunes in a hot air balloon, climb aboard a high-speed ride at IMG Worlds of Adventure or skydive over the Palm Jumeirah.

The soundtrack of tranquil Boa Vista is the sweet tweets of exotic birds. Maybe they’re chattering with loggerhead turtles or with the humpback whales that are known to splash around Boa Vista’s shallow waters. Work up a sweat and hike to the wreck of the Santa Maria, or explore the Duque de Braganca Fort, built to protect the Ilheu de Sal Rei from pirates. The windswept red and tan sand dunes of Deserto de Viana are awe-inspiring.

We've heard Toronto described as "New York City run by the Swiss," and it's true—you can find world-class theatre, shopping and restaurants here, but the sidewalks are clean and the people are friendly. The best place to start is literally at the top—the CN Tower, the tallest freestanding structure in the Western Hemisphere.
