This is going back a bit as our caravanning days are over, but I remember 'Le Ranolien' at Perros-Guirec as being a lovely site on the North coast. On the Southern coast 'Le grande Metrairie' had lots of facilities. It's near Carnac: a lovely area.
You'll be spoilt for choice wherever you go in Brittany..one of my favourite regions in France.
Best advice is to get the Eurocamp/Keycamp etc brochures and check out the sites, facilities & location and take it from there.
Happy caravanning!

Les Menhirs at Carnac Plage is worth a look. There's another thread currently running about Carnac Plage.
The Benodet area is also lovely.

we had a chalet here 3 years ago

at Le Pouldu-lovely area and the new owner has continued to make improvements to the site.

We stayed in La Grande Metairie last year (our kids were 8 & 10 at the time) and had an absolute ball. The site has great facilities with loads for the kids to do (we were there in July). We would highly recommend it.

Hi
Can anyone reccomend a camp site in brittany?
We are towing our own caravan to france for the 1st time & are looking for a well equipped site with pool/slides, kids club & near a beach.
Any other advise that you could give to a novice would be helpful.
Many thanks.

Have you been yet? what was it like for you?
if not when are you off?
Have you found a site ?
