Nicknamed the "Santorini of Spain," Altea draws laid-back travellers to the Costa Blanca with its hilltop old town and pebble beaches. Navy-domed landmarks and whitewashed walls stand out against Mediterranean skies, while three marinas provide plenty of offshore opportunities.

Ibiza’s premier party destination, Playa d'en Bossa draws A-listers and music lovers with its hip bars and thrumming clubs. But there’s more to this resort town than all-night raving–Ibiza’s longest beach harbours water sports facilities and relaxed restaurants, while a waterpark offers plenty for families, too.

Visitors who come to Ibiza’s energetic capital for its nightlife are treated to more than just thumping ultraclubs and celebrity sightings. By day, the harbour town is a sun-drenched sampler of Spanish-island style, with waterfront cafes, urban beaches, trendy boutiques, and even a UNESCO-listed fortress.

It’s nicknamed the Eternal City for a reason. In Rome, you can drink from a street fountain fed by an ancient aqueduct. Or see the same profile on a statue in the Capitoline Museum and the guy making your cappuccino. (Which, of course, you know never to order after 11 am.) Rome is also a city of contrasts—what other place on earth could be home to both the Vatican and La Dolce Vita?

Everyone who visits Paris for the first time probably has the same punchlist of major attractions to hit: The Louvre, Notre Dame, The Eiffel Tower, etc. Just make sure you leave some time to wander the city’s grand boulevards and eat in as many cafes, bistros and brasseries as possible. And don’t forget the shopping—whether your tastes run to Louis Vuitton or Les Puces (the flea market), you can find it here.

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.

Nestled at the foot of the Black Forest in South Germany, Baden-Baden is a chic destination for those who fancy a dip in its famous salt- and radon-rich thermal hot springs. The town has been a popular destination for so long that it's starting to show its age, but not to worry. It's still very classy, picturesque and well-maintained. (The Dame Julie Andrews of German spa towns, if you will.) Sporty types will find an abundance of opportunities to enjoy golf, tennis, horseback riding and skiing nearby in winter.

Over the centuries, many cultures have added their mark to this prized piece of land. Today, you can experience those influences firsthand by exploring Istanbul’s mahalles (neighbourhoods). From the holy sites of Sultanahmet and the 19th-century European elegance of Beyoğlu to the high fashion of Nişantaşı, the vibrant café society of Kadıköy and the football-loving streets of Beşiktaş, it’s easy to see why travellers say that Istanbul isn’t just one city, but many cities within one.
