The knee finally felt okay enough and the head was feeling good as well. So, it was time for another walk out in the countryside. The last (local) walk was okay, but only just. There was just too much built up area to be any kind of fun at all.
So, I trawled through the archives of the Dutch Forestry Commission and found a walk that suited me a lot more. It needed a drive to and from, but that was fine. Once I arrived at the parking lot I could not find the walk I wanted to do, but on an information board close by I found another walk that would be about equal distance (6 km). So, instead of the blue signs, I followed the yellow ones.
Some areas of the walk were also used by mountain bikers (I only saw the tracks fortunately) and there the paths were extremely muddy and difficult to navigate. But, mostly it was reasonably dry. As it was quite foggy any view that there might be, was ruined somewhat, but it was a good walk nonetheless.
At the end of the walk I found my blue signs, so I put that in the back of my head for another day. By the time I had finished my walk, I noticed the walk was not nearly as long as 'advertised' on the information board: it was 4,7 km max! A bit of a shame, but at least I got that in. On the Forestry's site it stated the walk was 5 km, so much closer to the real thing.
