u may be able to find others by going to the business department of a large estate agent in the area u r interested in, but afaik those 2 are the best. u shd also contat the BH&HPA as they shd be able to help u with advice etc..
campsites trade roughly in line with houses [going up & down], but u normally have to pay more than they may be worth on a commercial basis because lots of people buy them for a "lifestyle change". good luck.

Don't forget to leave a review of the French and other European campsites you have visited!
Why not contact the CC and the C&CC - they both have franchise types sites, if nothing else I am sure they would be able to give you plenty of good advice.

Pick up a copy of Daltons Weekly at your local newsagent or supermarket. It's a weekly newspaper that specialises in classified ads, mainly trade and business sales. I remember seeing caravan/camping sites when we were looking to buy a pub a few years ago. They also have a website: click here
