I need to put up the bill for our camp last friday. Two people, two tents and croissants delivered to our site in the morning by the site manager 19.60€. I left him the 40c change. A lovely bloke and a very nice site for those who don't demand all entertainment supplied pre-canned (here you make your own; sad that petanque boules weigh too much to cart around cycle-camping). Camping Le Penfaut, St Vincent sur Oust, Morbihan (Brittany), for those cycling the Brest-Nantes canal.
They also have a marquee with benches and tables and a shed with gas stove, microwave and fridge alongside for the lightweight campers. We were glad of that on the saturday morning, breakfasting while it rained!
