We prefer FL/CL as Siblu is Hasven Europe and the sites tend to be a bit bigger, busier and British!! Rory the Tiger n all that! We stayed in a Siblu site in St Jean de Monts (Le bois Masson) and had a good time but were glad we weren't there in peak season!! Saying that the sister Siblu site across the road looked lovely.(Le bois dormant)
If you're looking for recommendations here are our top campsites:
Camping Mane Guernehue in Baden, gulf of Morbihan in Brittany - fab site , best pool comples, loads of facilities for kids, can walk to village but you have to drive to a beach
Camping Acapulco - St Jena de Monts. in vendee not Brittany but great site, close to beach - can walk there and to local amenities. Close to major attractions like zoos, safari parks, Le Grand Parc and les dunes.
Camping les deux Fontaines in Raguenes BRittany. Hope it's fab cos we're going in Aug! Check out the website rather than the brochure picture as the brochure doesn't do it justice. Wlaking distance to beach again.
We also stayed at Canping Village la plage in Le Guilvenic Brittany. It was a bit basic pool and bar wise but nice layout and right ona lovely beach. It actually closed down on us at the end of the season so watch out if you're going in Aug/Sep!!
Hope you find one you like!!
