This time our hike in early January 2022 went to the flat plain of the Rhine valley north near Karlsruhe in Germany. We had chosen this route because it is a bit more relaxed to walk without climbs and also we did not know the area yet. The Rhine valley north of Basel is about 50 km wide and completely flat. Therefore, there are a lot of fields on this fertile soil, but also some forests. So we walked through this ancient cultivated area at almost 0 degrees Celsius in winter.
