mon français est très modeste, j'ai dû m'aider de DEEPL 
Between St. Tropez and Cannes? I remember Fréjus at least from the name...
I guess it was in 1963 when my parents did camping with us kids somewhere at the medeteranian coast, I still remember the beautifull cathedral at Marseille.
In the late 70's and early 80's I made camping by my self several times, where I visited St. Tropez, La Grand Motte, Montpellier and a couple of small villages on the way down to Perpingan as well as Clermont Ferrand.
Because I always had old cars, I did a lot of repairs during the trips, and learned the one and other repair shop.
In the 90's I spend a few days in Paris visiting several historical places, including one evening in the Lido Varieté (was interesting to see a show at least once), while in apx. 2005 I ferried a Cessna from North Germany to Cannes, then spending a day in Nice.
However, I keep the life style in the off-tourist locations very positiv in my mind
