As part of a First Class Europass(train) we took a boat from the dock in Lucerne to the other end of lake Lucerne. You then got on the cog railway to go the top of Mt Pilatus. From the top of the mountain you took a tram car down the other side and then a bus took you back into town. It was a great round trip day trip package.
My mother was born in Bad Tolz. My dad met her while he was stationed at the old SS Casserne there and they were married in Oberamagau. That side of the family lives near Tegensee at the base of the mountains. The last time I went back for Christmas and New Years, my uncle and I went up the Sielbahn to ski on the glacier. Once finished, we ate at the restaurant up there on top of the Zugspitze and then rode the cog train back.
