Jungfrau is a famous mountain in Switzerland. It is located in the southeast of Interlaken at an altitude of more than 4 kilometers. The train lasts about half an hour. It is said that the Jungfrau Mountain Railway, which transports tourists to the mountains, is a great engineering miracle of mankind in the early 20th century. Built between 1896 and 1912, the railway lasted 16 years. To avoid landslides and snowstorms, a fairly long part of the route was excavated in the tunnels in the hinterland of Mount Egg, standing on Girl Peak, known as European Roof , the most breathtaking panorama of the Alps can be seen at a glance. At the foot of the mountain, endless green, occasionally a little cattle scattered on the hillside, maybe the people are too rich, cattle and sheep farming and crops are not many, that is, neat and beautiful grassland, snow drifting on the top of the mountain, sometimes foggy sky, like fairyland.
