Cannes, France

Cannes is perched on what is arguably the most glamorous coastline, the French Riviera. The main event here is the invitation-only Cannes International Film Festival, where you can mingle in front of the Palais des Festivals as celebs work the red carpet. For other opulent year-round pursuits, get bronzed on the legendary, palm-lined La Croisette waterfront; browse the most upscale boutiques; and gather fresh vegetables, ripe fruit and local cheeses at the Forville Market. Go in search of peerless antiques at a classy flea market. Indulge in Michelin-starred restaurants. And of course, end the day with a cocktail in one of the city’s ultra posh bars, casinos and cafes.
