Set between Rome and Naples amid the so-called Ulysses Riviera, gorgeous Gaeta overlooks the beautiful Tyrrhenian Sea. Its history as a resort dates back to Imperial Rome. Nearby sites include the first-century BC mausoleum of general Lucius Munatius Plancus. Its old town is mostly medieval, showcased by narrow alleys, the massive 13th-century castle and the 12th-century Cathedral of Assunta e Sant'Erasmo. For relaxing, lovely and central Serapo Beach is a favored locale.

The coastal jewel of Javea is bookended by rocky headlands and is a prime example of old world meets modern energy. The "old town" district is filled with remains of walls built to keep out pirates, as well as a 14th-century church. Visit the beautiful white-sand Arenal beach, brimming with shops, restaurants and, in the summer, hopping beachside bars and nightclubs.

Woolacombe’s three-mile long beach is one of the best family beaches in the U.K. Build a castle in the clean sand, learn to surf, or go horseback riding on the beach. Boat operators offer fishing trips and tours—keep your eyes open for seals!

Celebrate the wonders of the land and sea in Gothenburg, Sweden’s second-largest city and home to Liseberg amusement park, the country’s #1 tourist attraction. Visiting Gothenburg Archipelago is a must, as is sampling everything from modern gastronomy to ‘fika’ to the fresh-caught wonders at Feskekörka (Fish Church). Be sure to take in the Gothenburg Museum of Art, stunning contemporary art at Röda Sten Art Centre, and – if you visit in August – the incredible Way Out West music festival.

Laid out by British architect Edwin Lutyens, the Indian capital is a striking modern metropolis. A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.

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.

Many tourists know Windsor for its casino. But if you dig a little deeper, you’ll find fascinating history here. Once an important stop on the Underground Railroad, Windsor became an important center of whisky production and, thus, a major smuggling port during Prohibition. (Apparently Al Capone liked his Canadian Club.) In summer, catch the enormous fireworks display at the International Freedom Festival.
