If you drive down the Moselle during Summer you’re bound to dance your way into a festival (consisting mostly of wine and music of course). Stop the car, find a bed at a local guest house or pitch your camper at one of the grassy grounds. Then stay in each town a few extra days.
Our pick is most definitely the Moselle over the Rhine. You’re likely to go days without hearing any English – it’s the villages where you’ll find the holiday goers of Germany and France drive their way through.
