Europe camping sites - comprehensive list
 

Although not specifically for bikers, I reckon that there will be campsites in this guide that will welcome riders:-
Alan Rogers Camping Guides - Camping in France, Spain, Italy, Britain

I used it some years ago for family camping out of the boot of a car (back in the days when it was in paper form only - there is an online search available now) and I always found the recommendations to be accurate and unbiased: hopefully they remain so.

You're right Dave; these aren't specifically for bikers. Many of these sites on your link offer electric sockets etc and seem most suited to caravans and cars - which you did many years ago, and you may not been back on a bike since then......... No mention of prices either....


Ta anyway

My tip to you is to use Municipal sites in France for the bike.
