Cannes is a city in France.
Very rich city full of luxury people and cars.
It's easy to get out of this city. The roundabout of the motorway E80 is connected with the city via Avenue du Campon and the Boulevard Carnot. From the train station there is a Bus 630 Valbon (frequency one each hour) that puts you directly before the roundabout. Stop in "Chemin Belvedere" or ask to the driver. Also you can take the Bus 1 from the same train station (frequency 10 minutes) but you will need to walk all the aAvenue du Campon around 1 km.
Accommodation and Sleep
It's hard to sleep for free in Cannes. Beaches are private property, so you will need to walk far away to find a spot. There is only one youth hostel behind the train station.
