The city tour of Düsseldorf can be completely visited in about half a day, of course, this is a flower-watching punch card. From the central station, cross the King's Avenue, the old town, about 30 minutes walk to the Rhine. The season we went to was May, or it was a bit cold in spring, the wind was a bit big, if the weather was good, it should be quite pleasant to stroll on the Rhine River. And there are often various large outdoor entertainment activities here, and the riverside has become an activity gathering point, which is very interesting.
