Just a word of warning about the Dordogne, we were on the Municipal Campsite at Bergerac once in our Caravan days and during the early hours of the morning we were woken by the Guardian and told we had to move our van PDQ as the River was flooding and had risen about 30 feet in a few hours, it was good fun though, all helped each other move to higher ground , this was in June . so beware if you park up close to any river they can change quickly, you can generally park in town squares in France too with no bother, we did this once to find that when we woke up next morning we were surrounded by the local Market that had formed up in the early hours and we were stuck, we couldn't get out, no problem we just enjoyed the Market and made tea for some of the traders, they enjoyed our English tea, the French are great people and easy to get along with especially if you try to speak French.
