This is precisely the sort of place for which the verb flâner (to dawdle, saunter) was invented. Head to this famous waterfront promenade—which runs for 1.6 kilometers (1 mile) from its western terminus by the Palais des Festivals—and allow the esprit de Cannes to take over. Stroll among the palm trees and flowers and crowds of poseurs (fur coats in tropical weather, cell phones on Rollerblades, and sunglasses at night). Continue east past the broad expanse of private beaches, glamorous shops, and luxurious hotels (among them the wedding-cake Carlton, famed for its see-and-be-seen terrace-level brasserie). The beaches along here are almost all private, but it's worth forking out the money to get the total Cannes experience.
