If you go to Switzerland, you can't miss sightseeing. If the weather is good, you must go to Tuen by steam boat. It's beautiful and beautiful. The lake is very clear and green, the distance is the Alps snow mountain, and the villages on the shore are scattered. It's so enjoyable to enjoy the beautiful scenery in the sunshine on the deck. The whole voyage is from Tuen to Interlakense, the first half of which is the most beautiful. For Spitz, Interlaken recommends waterways.
