French IGN maps

[Loki]

Hi all, I am slowly putting together a 2-3 day bivvy trip over to Brittany using a mix of gravel roads and tarmac, I see France has their version of OS maps, IGN. Does anyone have any experience using them with regards to detail and quality?

I've always found them okay. Not OS but perfectly serviceable.

As with Stu, they are ok. Contours can be a bit confusing.

[Taylor]

Pretty much agree with those two.

Cheers all, I had heard mixed views on them, pretty excited about the trip already.

Google Tro Bro Leon and try to find the route (strava?). It’s a French professional road race that takes in a lot of gravel in that area. May be worth a punt?

In case you didn't see, those maps are online at https://geoportail.gouv.fr

I personnaly select the three "Carte IGN" "Cartes IGN classiques" and "Photographies aériennes" in the upper left "Cartes" menu, then I change between then in the right menu where you see a layer icon.
