Like the route, however I think it should be avoided after lots of rain. A couple of patches were a mud bath and virtually impassable.

One of the simplest tours in Limburg. However rising but not overdone, with some difficult technical and steep (still wet and therefore hardly cycling for me). Rest very nice trip, but more regular bicycle or walking.
