Ryusen, Switzerland, takes a boat to the town of vitznau, and then hikes along the roadside sign for about 15 minutes to the hillside by gear train. The wind on the hillside is so strong that you have to wear a hat. If you don't have a headache, you can have a simple lunch in the restaurant of the viewing platform on the hill. When the weather is clear, you can choose the cable car to the town of Weggis and take the train first. Down to the kaltbad station, you can take a cable car to the town of weggis. After visiting the town, you can take a boat back to Ryusen. The whole traffic is about 120 Swiss francs, expensive but worth it.
