There must be Jiuzhaigou in the list of places you must visit all your life. Although Jiuzhaigou has different scenery in four seasons, even in sunny and rainy days, it is worth going again. But after all, Jiuzhaigou is on the plateau of northern Sichuan. There is no railway. It takes about 8 hours to travel from Chengdu. As a person who has been to Jiuzhaigou countless times and can play around Jiuzhaigou with his eyes closed, I now solemnly tell you that if you only go to Jiuzhaigou once in your life, you must follow this strategy, and you will not regret playing inside and outside for a long time. The length of the three ditches in Jiuzhaigou scenic area, Shuzheng ditch, Rize ditch and Zezawa ditch, adds up to 50 km in one way. So if you want to visit Jiuzhaigou one day without regret, you should enter ditch earlier. Fortunately, the roadway in the scenic spot is reasonably designed, the route is time-saving, you can enjoy the beautiful scenery close to you, and you can return to the station whenever you want to take a bus. In fact, when you first get on the sightseeing bus, the friendly Tibetan staff will tell you how to see all the sights in a day by bus. If you enter the ditch later, she will also tell you which scenic spots can be avoided so as to save valuable time for more elite scenic spots.
