I visited Lucerne as part of a tour organised by Treyn Holidays. We had about 5 hours free time in Lucerne. The weather unfortunately was overcast and therefore a visit to Mount Pilatus or Rigi was not possible and instead I, and others, took one of the regular service boats for a 2 hour trip around the lake calling at various stops, the furthest being Stansstad. The boat ride was smooth, the hot chocolate (CHF 4.20) excellent and the boat (Mount Pilatus) was clean and comfortable. Afterwards I walked over the Chapel Bridge (a must) and meandered through the old town.
