First of all, I need to take the train to Interlaken. Here I would recommend using the local Swiss transportation app [ SBB Mobile ] to enter the starting point and end point. The time period and the information replaced are particularly clear. The Swiss Pass is expensive and we chose a single time considering that the train is not very available next time, so note that the tickets marked supersaver are limited to rides. Tickets are more expensive to buy on the spot, about RMB 1400, I am in advance on the official website, can be about 200 cheaper, the day of travel can go to the station with the QR code to change tickets on the bus. From Interlaken East Station, there are two routes to Jungfrau: Route A Interlaken East Station - Greendewa Clashede - Jungfrau B Route Interlaken East Station - Lauterbrunnru Clayde Jungfrau - Jungfrau is super recommended to go up the mountain A down the mountain B like this, or go up the mountain B down the mountain A, You can experience different scenery. Photo sharing: Sphinx Full Landscape Platform overlooking the panoramic view of the Swiss snow-capped mountains, the cliff is at the foot of the hollow ground, and the entire observation deck feels suspended in mid-air. Observation Deck No. 9: The weather was very good on the day we went, because the snowstorm closed for half a month and the room exterior viewing platform was reopened. You can check in the Swiss flag and take pictures here. Glass Observation Deck: There is a 360o glass panoramic platform from the Sphinx Observation Deck, and you can see the snowy mountains outside the window. Finally, be sure to keep the ticket stubs, and the ticket check will send a lindt chocolate that Jungfrau and the Swiss Railway Agency cooperate with. Interested friends can also get a Jungfrau passport at Jungfrau station, you can cover the last page with a steel stamp. Be sure to watch the weather or the white patch will be very disappointing.
