We stayed in Cannes a few years ago and drove to Monaco via St Paul de Vence. It's a lovely town with great views. Chagall is buried in the local cemetery and Bill Wyman owns a place, I think the Stones recorded something there. On the way back to Cannes we drove along the coast, which is dotted with beautiful beach towns. I thought St Jean Cap Ferret was particularly pretty and have been plotting a return trip someday....
