Roberto, a great host, took us young & senior folks on a fun tour through rural Lucerne. This is not your typical sightseeing tour visiting the Kapellbrücke, Lions Monument etc. Rather, the tour is taking you through Lucerne and the Agglomeration. You'll see where locals live, where they garden, where they take a walk, where they play & watch soccer. And where they drink water when they are first. All public fountains in swiss towns are fed with high quality drinking water - unless marked with "KEIN TRINKWASSER" (German, in the ItalianFrench parts of Switzerland the equivalent is written in Italian/French).
And of course, the tour also offers very scenic views of the lake and the surrounding mountains.
