Thanks to Complete France for this list of 16 Traditional Villages in Brittany You Have to Visit.
Île-de-Batz
I still haven’t seen all of them. I’m missing four: Bécherel (Ille-et-Vilaine), Pontrieux (Côtes d’Armor), La Roche-Derrien (Côtes d’Armor) and Pont-Croix (Finistère). But for the twelve I’ve seen, I agree that they are all worth visiting.
Landévennec
I’d also add a few more to the list, starting with: St.-Michel-en-Grève (Côtesd’Armor), Lanildut (Finistère), Daoulas (Finistère), Landévennec (Finistère), Saint-Cado (Morbihan), Locmariaquer (Morbihan), La Roche-Bernard (Morbihan) and the main towns on Île de Batz (Finistère), Île-aux Moines (Morbihan) and Île d’Arz (Morbihan)…. and I am sure I’ll keep adding to the list!
