There are about eight kilometers of sandy beaches in the festival capital. Most of them are paid. For example, the best beach in Cannes, Martinez, is available for 28 EUR. On the municipal beaches, for example, "Macé" (Plage Macé), located near the Palais des Festivals, access is free. But you will have to pay for a sunbed and umbrella - about 7 EUR each for a day.
If you come on vacation in May, right on the beach you will find a giant screen. On it some films of the Cannes Film Festival are shown free of charge for guests and residents of the city.
The nightlife in Cannes is no less, and sometimes more active than the daytime. From 19:00 to 3:00 the Palm Beach Casino and Le Casino Croisette are open. In the latter do not be lazy to clarify the rules of the game before you bet. They are different from the usual. Without a passport you can not even go to the casino. Gambling establishments in France are obliged to identify their visitors.
