Have a look at Camp de Lety in Benodet. Approx1.5 hours drive from Roscoff via Quimper. My wife and I spent two weeks on this site and had a brilliant holiday. Beautiful clean site opening onto the beach and a leasurly stroll along the beach path to Benodet. Also plenty of interesting paces close by to visit such as Quimper with its old world town and fabulous cathedral, Concaneau - an old fortress port, etc. We booked the complete package to include the ferry crossing from Plymouth with select sites at Abergaveny - www.selectsites.co.uk. All we needed was spending money all else taken care for such as insurances, breakdown cover, site fees, etc. We sailed from Plymouth as it was our first time abroad with the caravan and thought it would be easier to do most of the driving oin this country on familiar road conditions. The ferry crossing was a few hours but we enjoyed it an accepted it as part of the holiday. One piece of advice if taking a night time crossing book a cabin and not the reclining chairs - they are uncomfrtable and the room is noisy - virtually impossible to get any sleep. Good luck and enjoy your venture abroad - we did. PS excuse my French spelling.
