With Cologne humor in the baggage you leave the cathedral city and cycle along the banks of the Rhine till you reach the medieval town of Zons. This fortress city with a city wall still entirely preserved is also called the Rothenburg of the Rhineland'. It features the mighty Rhine Tower from 1388, the Juddeturm with baroque dome and a windmill with a wooden mill from the 17th century. You continue cycling the Rhine cycle path and in the afternoon you reach Düsseldorf's Old Town, also known as "the longest bar in the world'. This expression leads back to the 250 pubs, restaurants and bars, lined up in the streets of the old town. Relax with a real Düsseldorf Altbier at Castle Square and enjoy a wonderful view of the Rhine.
