The best time to visit Cannes for camping is during the shoulder seasons from spring through fall, as the balmy sunshine of the French Riviera lasts during these times. It's best to avoid the overflow of tourists through July and August, as well as during the annual Cannes Film Festival in May, when there are big crowds, full campsites, and high-season prices. Advance bookings are essential if you visit at these times. You can also explore different options for camping near Cannes on Hipcamp.
