Campsites on the South Coast of France

Garydoyle63

We have a few weeks at the end of June/ early July where we are staying I the south of France in the motorhome. We are planning on staying around the Verdon area. However, we would like to take a few days out to visit the south coast (Cannes, Nice, Monte
Carlo area, although not fussy where at moment -just want to see it). 

Just looking for any tips on campsites, what to avoid or where to go.

Many Thanks
