I’ve been to France a few times but still haven’t seen most of the places you mention but have been to a lot of fantastic places not on your list. The Dolmen and Menhirs near Carnac are worth seeing. I found them much more impressive than Stonehenge. If you’ve read any Jules Verne, Nantes and L’ile Des animaux is like nothing else I’ve seen in the whole world. Strasbourg, mittelbergheim , Colmar and the entire Rhone Valley are beautiful but you are nowhere near there. I loved Carcassonne and Mont St Michel, Montpelier and Nîmes but i think they are the only places I’ve been on your list. Oh and Paris of course. There’s a website called Secret Paris that I love. I planned to visit some of the places mentioned there in my last week in Paris but I never got there.
