Found this site and map where you can type in the area and it shows you where you can/cannot fly officially - France regulations.
Hope it helps - https://www.geoportail.gouv.fr/carte

Change map carts to geologique and there is a Drone map zone overlay.
Just sharing in case anyone hasn't seen it who may be visiting etc

Thanks for this info. Last week before setting off to France I checked my location and the website worked perfectly. Now that I am back home, I want to check on something and cannot get the site to work in the same way.

My screen differs from the image that you have posted in that I do not have the option to show restrictions for drones.

Could you try it again please to see if it is still working for you.

Thanks

Hmm... Looks like NATO/military has claimed the chunk of the Beskai Bay and Mediterranean Sea
