18 May - Rigi
The original plan was to hike Pilatus today. However, the cogwheel and trail are not yet open. Instead, we took a boat to Vitznau and the cogwheel train to Kaltbad. From there we hiked the rest of the way to Rigi Kulm (summit) and had lunch. Then we took a different cogwheel train down to Arth-Goldau and a train back to Luzern. Unfortunately, the weather was foggy at the summit and there was no view.
