Carnac is lovely with a lovely church and a market on Wednesday and Sunday ok short drive to queberon array and trinite well worth it beaches don't accept dogs bit of a down for us but as it was end of season we were ok in the evenings with dogs good market on carnac plague Everyone was very friendly they are proud of Breton
Mont St Michel worth a visit, Old walled town of St Malo worth a visit great restaurants there, The local town of Dol de Bretagne has some good places to eat and is full of old world charm Cathedral also worth a look
First time to this coastline, but have been elsewhere (Carantec, La Trinite sur mer). A great variety of environments to explore. Area is excellent for coastal walking, and all towns seem to have plenty of walking brochures for inland as well. Lots of good seafood, galettes, crepes. A very relaxed way of life in general. We like the enclos in the Morlaix area.
