I have to organise a trip next year from Calais to Colditz on nice roads not motorways and include the Harz mountains. Any suggestions please.
Going from Calais to Colditz via the Harz area is like going from Dover to Bristol via Newcastle...You'll loose a lot of time going from Calais to Harz mountains...I'd prefer to go via the Ardennes, Eifel, Sauerland, Thuringhia to Saxonia...You'll miss the Harz mountains but it's much better to take this way than travelling through a busy ( Ruhr area) part of Germany and a boring part ( Lower Saxony ) to reach the most northern mountains of Germany...
