How much poorer would European literature be if he didn't exist: the heroic King ARTHUR has - at least in the fantasy world of countless authors who have told his story over and over again for centuries, and above all in their ever-fascinating readers or listeners - conquered a permanent place in the collective memory of people. Everyone can decide for themselves what historical connection this hiking highlight has with the person of the legendary king. But the main thing is: the myth lives on!

There are some stunning aspects to this hike. Amazing huge boulders, beautiful trees and waterways. HOWEVER, during our hike in June 2024 there was logging on parts of the track and significant number of trees down. Also (or perhaps in part because of these issues) the track was not always easy to follow. In particular the starting point, which extended off of private driveways shortly after creperie. No signage to direct walkers. We were only a lento complete this walk by turning around and walking in reverse direction of track. Not a problem with reversing direction, but it was quite stressful working out where track was.

Many centuries ago, our ancestors discovered the possibility of harnessing the power of the elements - which on the one hand were helpful and useful, but on the other hand could also be a threat as untamed forces of nature - for different purposes and thus did without human or animal muscle power can. Such mills are a good example of the human engineering skills of earlier generations: the heavy millstones with which, for example, grain was ground into grain or oil was pressed, could be powered with the help of the wind or - as here - water.
