Camping by smlsmall van or large estate car mpv, overnight without problems in spainSpain, beach parking areas and beach!, especially castelCastel de ferroFerro area almeria, Almeria coast line, you come across a few camper vans and also local rod fishermen night fishing forming tents with umbrellas and the like.
France - parkedParked all over BUT discreet!! Places in villages as in centrecenter parking ,back back lane, or grassed parking areas, some have designated areas in small towns, there's also lay-byes that are well off road in places, on the main route's lay-byes are used by many and some have toilets, I am always aware to park either where others are or completely out of vision for safety, I have only been moved once, there was a big boules tournament following day, I should have noticed adverts, so always check!!! Could end up in middle of a car boot sale in morning, thats neenbeen done!!
So really just use common-sense and respect.
Happy days to all, Col
