For the 1984 summer holiday, we spent a week in Carnac in Brittany and then ventured a bit further south well, we drove down to the Vendee and St Jean de Monts. A lovely place as I recall, with a vast sandy beach being reached through a pine wood.
As for Carnac, you can probably imagine how interested a 16 year old boy was in standing stones. It took a long time for me to be able to utter the word “Carnac” without the word “sodding” in front of it.
