Soufriere's backdrop of the Pitons, sea and rainforest provides a picture perfect setting for a visit to this laid-back and relatively undeveloped town in the south of St. Lucia. Considering that its name is French for "sulphur," it should be no surprise to discover the wealth of hot springs and mineral baths. Other great spots to visit include Diamond Botanical Gardens, a slew of pretty beaches and the bike trails that wind through sugar plantation Anse Mamin. Rent a car to see the town.

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.

A coastal town just 20 miles west of Lisbon, Cascais was once a small fishing village, but its idyllic scenery attracted the attention of artists, writers and expelled European nobility in the 20th century. Today, it still attracts high society, but all society comes in force to enjoy the gorgeous beaches and adventure options like sailing and surfing. The Conde de Castro Guimarães Museum, a former palace, is now open to the public and displays an impressive collection of art and artifacts.

San Diego embodies laid-back California culture, complete with a Boardwalk, surfing communities, and outstanding Mexican food. Breathe in the fresh ocean air at Sunset Cliffs Natural Park, then gobble down a fresh fish taco at a La Jolla seafood joint. The naval aircrafts at the USS Midway Museum will have you standing at attention. A free Sunday concert at the Spreckels Organ Pavilion is the perfect way to unwind after a Saturday night bar-hop in the thumping Gaslamp Quarter.

Stroll Las Ramblas and enjoy Barcelona's unique blend of Catalan culture, distinctive architecture, lively nightlife and trendy, stylish hotels. You'll find Europe's best-preserved Gothic Quarter here, as well as amazing architectural works by Gaudi.

Look no further than the rambunctious La Boqueria market, where you can stock up on local delicacies.

Palma, the economic and cultural hub of Majorca, is a delightful base for exploring the island's many gold and white beaches. A former Moorish casbah, or walled city, Palma's Old Town is an appealing maze of narrow streets that are a delight to explore on foot. Hop on the Soller Railway for a 17-mile scenic trip, visit 14th-century Bellver Castle and the museum of contemporary art, and check out the nightlife.

One of the most popular regions in Italy, Tuscany stretches from the Tyrrhenian Sea to the Apennines. Its main cities include Florence, Pisa, Siena, Lucca, Arezzo and Livorno. Drive between stunning sites like Florence's cathedral and Uffizi Gallery and the Leaning Tower of Pisa. Or join a bike tour and pedal past sun-baked olive groves and vineyards. Don't miss the towers of San Gimignano or serene northern hill towns. For a more modern take, hit one of Florence's hip clubs, such as Space Electronic.

The Mediterranean's biggest island is separated from the mainland by the Strait of Messina. A mountainous spot, Sicily's coast and its small islands sit at the foot of volcanoes, including Etna, Stromboli and Vulcano. The Greeks, Romans, Normans and Catalans all left their mark on the island in the form of Byzantine palaces, Gothic castles and Baroque flourishes in capital Palermo. Most larger towns offer interesting museums, but Etna and the Hellenic temples in Agrigento offer particularly unique sights.
