Cannes is first of all a bay: La Croisette and its palm trees on one side, the hill of Le Suquet on the other, and the Lérins Islands floating just offshore. Between them, the Palais des Festivals is a reminder that the city lives to the rhythm of major international gatherings, from the Cannes Film Festival in spring to trade events such as MIPIM and Cannes Lions. The rest of the year, people come for the sea, the market and the light.
Everything can be explored on foot, but traffic and parking quickly become difficult in high season or during events. With a private driver you are dropped at the Old Port or as close as possible to your hotel, with no space to hunt for, and you can extend the day to Antibes, Mougins or Grasse, or stay for dinner and return to Nice without driving.
