To Jungfrau Peak, please pay attention to https://www.jungfrau.ch/zh-cn/ Here is a real-time weather camera on the mountain. You can see the weather conditions on the mountain, so that you can grasp the information and avoid leaving regrets because of bad weather. To get to Jungfrau you need to buy tickets. Swiss pass can only be used to Wengen Ongen. It is suggested that you buy the tickets directly in Interlaken Ost. There are many ticket buyers. They need to queue the number of tickets, which is similar to the Bank Queuing system. Everyone can give a 75% discount on the ticket, and calculate 134.5 CHF. If a child has a ticket, the child is free. Here we need to remind you that you can buy seats with reservations, 5 CHF / person, a total of 10 yuan. Buying a seat ticket can save you from queuing for the Jungfrau train. There are different routes up and down, so you can enjoy different scenery on both sides. The ticket buyer will tell you. Interlaken Ost Lauterbrunnen (20 minutes) changes to Lauterbrunnen Kleine Scheidegg (40 minutes or so) opposite the platform. Here you need to change to Jungfrau train and show your ticket to Jungfrau. As mentioned earlier, if you have seat reservations, you can go straight to the green lane and get on the bus quickly. If not, you need to go through the red queue area and wait for others to get on. The last train runs for 35 minutes, so the total time to go up the mountain is about 2 hours (plus transfer waiting time). The train will stop at Eigergletscher station for a few minutes, just to take a picture of you or something, and you can get off the train. Note that it's cold here, because in the tunnel, you need to wear a coat. When the train finally reached the top of the mountain, it was also in the tunnel. Everyone got off and followed the signs to play with the scenic spots. There is a large area of snow for you to play, pay attention to bring sunglasses, the temperature is much lower than Mount Richard, only 7-8 degrees. You can play in the mountains for about 2 hours, including ice sculptures, snow flakes, shops and so on. Downhill or back to the tunnel station, similarly, there are reserved green passages, no red passages after boarding. The downhill train arrives at Kleine Scheidegg, a transit station where trains from both directions converge. You have time to rest here for a while. When you go down the hill, pay attention to the direction of the train. One is to Lauterbrunnen, the other is to Grindwald. We need to go to Grindwald, and then Grindwald_Interlaken Ost. It takes about 6 hours to play Girl Peak.
