Italy's vibrant capital lives in the present, but no other city on earth evokes its past so powerfully. For over 2,500 years, emperors, popes, artists, and common citizens have left their mark here. Archaeological remains from ancient Rome, art-stuffed churches, and the treasures of Vatican City vie for your attention, but Rome is also a wonderful place to practice the Italian-perfected il dolce far niente, the sweet art of idleness. Your most memorable experiences may include sitting at a caffè in the Campo de' Fiori or strolling in a beguiling piazza.

Elba is the Tuscan archipelago's largest island, but it resembles nearby verdant Corsica more than it does its rocky Italian sisters, thanks to a network of underground springs that keep it lush and green. It's this combination of semitropical vegetation and dramatic mountain scenery—unusual in the Mediterranean—that has made Elba so prized for so long, and the island's uniqueness continues to draw boatloads of visitors throughout the warm months. A car is very useful for getting around the island, but public buses stop at most towns several times a day; the tourist office has timetables.

The colorful facades and pedestrians-only calata (promenade) make Portovenere the quintessential Ligurian seaside village. As a UNESCO World Heritage Site, its harbor is lined with tall, thin "terratetto" houses that date from as far back as the 11th century and are connected in a wall-like formation to protect against attacks by the Pisans and local pirates. Its tiny, carruggi (alley-like passageways) lead to an array of charming shops, homes, and gardens and eventually to the village's impressive Castle Doria high on the olive tree covered hill. To the west standing guard over the Mediterranean is the picturesque medieval Chiesa di San Pietro, once the site of a temple to Venus (Venere in Italian), from which Portovenere gets its name. Nearby, in a rocky area leading to the sea, is Byron's Cave, a favorite spot that the poet loved to swim out into the sea from.

Cannes is pampered with the luxurious year-round climate that has made it one of the most popular resorts in Europe. Cannes was an important sentinel site for the monks who established themselves on Île St-Honorat in the Middle Ages. Its bay served as nothing more than a fishing port until in 1834 an English aristocrat, Lord Brougham, fell in love with the site during an emergency stopover with a sick daughter. He had a home built here and returned every winter for a sun cure—a ritual quickly picked up by his peers. Between the popularity of Le Train Blue transporting wealthy passengers from Calais, and the introduction in 1936 of France's first paid holidays, Cannes became the destination, a tasteful and expensive breeding ground for the upper-upscale.Cannes has been further glamorized by the ongoing success of its annual film festival, as famous as Hollywood's Academy Awards. About the closest many of us will get to feeling like a film star is a stroll here along La Croisette, the iconic promenade that gracefully curves the wave-washed sand coastline, peppered with chic restaurants and prestigious private beaches. This is precisely the sort of place for which the French invented the verb flâner (to dawdle, saunter): strewn with palm trees and poseurs, its fancy boutiques and status-symbol grand hotels—including the Carlton, the legendary backdrop to Grace Kelly in To Catch a Thief —all vying for the custom of the Louis Vuitton set. This legend is, to many, the heart and soul of the Côte d'Azur. 

At first glance, it really doesn't look all that impressive. There's a pretty port with cafés charging €5 for a coffee and a picturesque old town in sugared-almond hues, but there are many prettier in the hills nearby. There are sandy beaches, rare enough on the Riviera, and old-fashioned squares with plane trees and pétanque players, but these are a dime a dozen throughout Provence. So what made St-Tropez an internationally known locale? Two words: Brigitte Bardot. When this pulpeuse (voluptuous) teenager showed up in St-Tropez on the arm of Roger Vadim in 1956 to film And God Created Woman, the heads of the world snapped around. Neither the gentle descriptions of writer Guy de Maupassant (1850–93), nor the watercolor tones of Impressionist Paul Signac (1863–1935), nor the stream of painters who followed (including Matisse and Bonnard) could focus the world's attention on this seaside hamlet as did this one sensual woman in a scarf, Ray-Bans, and capris. Vanity Fair ran a big article, "Saint Tropez Babylon," detailing the over-the-top petrodollar parties, megayachts, and Beyoncé–d paparazzi. But don't be turned off: the next year, Stewart, Tabori & Chang released an elegant coffee-table book, Houses of St-Tropez, packed with photos of supremely tasteful and pretty residences, many occupied by fashion designers, artists, and writers. Once a hangout for Colette, Anaïs Nin, and Françoise Sagan, the town still earns its old moniker, the "Montparnasse of the Mediterranean." Yet you might be surprised to find that this byword for billionaires is so small and insulated. The lack of train service, casinos, and chain hotels keeps it that way. Yet fame, in a sense, came too fast for St-Trop. Unlike the chic resorts farther east, it didn't have the decades-old reputation of the sort that would attract visitors all year around. For a good reason: its location on the south side of the gulf puts it at the mercy of the terrible mistral winter winds. So, in summer the crowds descend and the prices rise into the stratosphere. In July and August, you must be carefree about the sordid matter of cash. After all, at the most Dionysian nightclub in town, a glass of tap water goes for $37 and when the mojo really gets going, billionaires think nothing of "champagne-spraying" the partying crowds—think World Series celebrations but with $1,000 bottles of Roederer Cristal instead of Gatorade. Complaining about summer crowds, overpricing, and lack of customer service has become a tourist sport and yet this is what makes St-Tropez—described by the French daily newspaper Le Figaro as the place you can see "the greatest number of faces per square meter"—as intriguing as it is seductive.

The fishing village of Sète serves as gateway to Montpellier, in the North. Other noteworthy destinations in this area include Carcassone, Aigues Mortes, the Abbaye de Fontfroide, and Pezenas. For a look at the real fisherman's life, however, stay right where you are. Sète is the Mediterranean's biggest fishing port. Canals winding through town make it fun to stroll around, and there are a number of good walking paths leading to the beach (about 30 minutes to the west). Although it's small and unspectacular, Plage de la Corniche has calm, pristine waters that are perfect for swimming. For a panoramic view of the area, climb Mont St-Clair or Les Pierres Blanches and pick a beach to settle down on.

The infinite variety of street life, the nooks and crannies of the medieval Barri Gòtic, the ceramic tile and stained glass of Art Nouveau facades, the art and music, the throb of street life, the food (ah, the food!)—one way or another, Barcelona will find a way to get your full attention. The capital of Catalonia is a banquet for the senses, with its beguiling mix of ancient and modern architecture, tempting cafés and markets, and sun-drenched Mediterranean beaches. A stroll along La Rambla and through waterfront Barceloneta, as well as a tour of Gaudí's majestic Sagrada Famíliaand his other unique creations, are part of a visit to Spain's second-largest city. Modern art museums and chic shops call for attention, too. Barcelona's vibe stays lively well into the night, when you can linger over regional wine and cuisine at buzzing tapas bars.
