If you are looking for camping in the Alpes-Maritimes area, I have stayed in "Camping Caravaning Les Cigales" 505 ave.de la Mer,06210 Mandelieu-la-Napoule. wwwlescigales.com.
Its right in the centre of the town but yet quiet and safe enough. Its a great base to visit the Corniche, Cannes and Monte Carlo. I stayed there a few years ago when at the Formula 1 race. Restaurant on site.Bus stops at the gate.A few minutes walk to the beach.
Of course the start of the "route des grandes Alpes" is close also.
