This is a good route to open the throttle as most of the corners are well marked (unlike France). The speed cameras are of no interest to bikers in Germany as they only take photos from the front of the bike HE HE. It can be hazardous at this time of the year because of the low sun beaming through the trees and the odd wet patch (I don't mean in the leathers) so watch out.
A pleasant road following a river valley through wooded, hilly countryside. Some nice bends as well. An enjoyable ride!
