Can anyone recommend campsites - France related

[CisMyArse]

Driving with family from Calais to Villefranche (taking a fortnight) but we'd like to explore eastern France. I've spotted a Castels and a few Yelloh campsites, but can anyone recommend some beautiful sites/spots to stay? Merci!

We stayed at Les Castels Chanteloupe on a stopover last year, we liked it so much we've booked a fortnight there this summer. I don't know if Chanteloupe is on your route but if it is any indication of the general standards of the Les Castels sites I would highly recommend them. Spotlessly clean, great facilities and loads going on

Which villefranche is it?
