A nice route which gets better from Lenwade a good road surface on the whole with some nice corners. Watch out for farm traffic and also the coppers like to sit in Lenwade waiting!
Cannes - Grasse - Castellane section: Done this route a few times now on the way to the Grand Canyon. Excellent ride, with good visibilty on fast corners, made for Blades and R1's. Also known as Route Napoleon.
