If you go in France :
Where you need to go because it's dope as fuck :
- Pont de Normandie : https://fr.wikipedia.org/wiki/Pont_de_Normandie
- Viaduc de Millau : https://fr.wikipedia.org/wiki/Viaduc_de_Millau
- Presqu'ile de Quiberon : https://fr.wikipedia.org/wiki/Presqu%27%C3%AEle_de_Quiberon
- Obviously South of France especially Camargue.
Avoid at all cost :
- Paris, cause it's worst than your worst nightmare to drive in. Unless you really want bragging rights on the avenue des champs elysées.
- Marseille. Nuff said !
Have a lot of fun !
EDIT : Just read your profile, didnot knew you were from Japan. I've been dreaming to go to Japan since forever ! Hajimemashite ! You'll find that France is the second manga market after japan ^^
