One could not be faulted for saying that Zurich is not really a natural excursion when on a journey from Mainz to Paris; however there are direct trains between all three cities, and it was cheaper to travel from Zurich to Paris than from Mainz to Paris, so work did not complain. I had visited Zurich previously in 2011 and my memories of the city were that it was pretty, but that it also stank of money which really put me off. Having visited Switzerland somewhat more extensively since then I wanted to give it another go, not to mention I was very keen to visit the nearby Rhinefalls, which are the largest in Europe.
