Assuming you have`nt already gone, go look for "LAND" magazine (french) they have really good tips for off-road stuff in France. If you get to Pyrenees, buy a carte de randoneer(walking ) map, really good info. Some of the routes that were Cathar or shepherd paths are negotiable with care and go on for days,in low ratio, forget trying them with a L322 and road tyres, grown men only! Germany has some good stuff but they get snakey if you ask for help if stuck, "vot are you dooink" etc, dont try to explain, just go. Spain can be a saga all on its own, they filmed"good bad and the ugly" there for good reason, no people. you can do Pamplona to Madrid off road but as previous, no L322`s. Good luck and have fun but go prepared.
