I know there are some "biggies", like Pilatus and Rigi, but I'd be curious to know the experiences of others. We will likely get a 3-day pass (and will hope for perfect weather; in Luzern the last week of May), and the choices are many. I realize folks have different interests but I'd like to hear from those who have used the pass, especially at or near the same time of year. We'll be coming from, and returning to, Strasbourg after our time in Luzern.
Many thanks!
