Day 16 - Early breakfast at local bakery before setting of at 8.45am for Zons. Next on route was Bonn, however we skirted Bonn due to route following river side with no diversions. Arrived then into Cologne where we had lunch and visited the cathedral (this is the number one visited tourist site in Germany). Made good time to Zons thanks to a local gentleman who guided us through the Ford works nr.Leverkusen. We would have been completely lost without his help. As result of this we reached Zons early so decided to carry on to Dusseldorf which we reached about 5 ish. Took a further hour to locate a hotel. Dusseldorf was busy due to Exhibitions in the city. Milage covered today 63 without rain .
