Sichuan-Tibet line (Chengdu-Lhasa section of National Highway 318), it is the highway with the most diverse geological structure in the world, with an altitude difference of more than 4,500 meters, and the highest altitude point is more than 5,000 meters. It is known as the most beautiful self-driving route in China. , across the rapids, along the way there are many snow-capped peaks, vertical and horizontal river valleys, rugged roads, and vast forests. It is really beautiful.

There are many familiar scenic spots along the way, such as Daocheng Yading, Hailuogou, Siguniang Mountain, Millennium Ancient Salt Field, Ranwu Lake, Midui Glacier, Taohuagou, Lulang... These places are very beautiful, but if you want to discuss And the highest place on this highway is Dongda Mountain.

Dongda Mountain is located in Zuogong County, Chamdo, Tibet. I remember that when I went there a few years ago, the altitude on the road sign was 5008 meters, but when I came here again last winter, I found that the road sign here had been changed to 5130 meters. It is said that It is the latest survey and mapping result, and it is the highest place on the Sichuan-Tibet line.

When the Sichuan-Tibet line comes here, you can really appreciate the feeling of the roof of the world. Although Gongga Mountain, Siguniang Mountain, and Genie Mountain in Sichuan are all high mountains over 6,000 meters, as ordinary travelers, they usually only reach 3 Overlooking from a height of -4000 meters, it rarely reaches a height of more than 5000 meters.

That’s why when you reach Dongda Mountain at 5,130 meters, you don’t know what the restricted area of ​​life is. Most people will have altitude sickness, and some people may even experience dizziness and fatigue. Running and strenuous exercise is not allowed here, otherwise the altitude sickness will be exacerbated.

There is a free parking lot on the top of Dongda Mountain. It was winter when we arrived, and there were no other tourists at that time. There were wild donkeys running by on the mountain. Although we can’t see the specific species, we can see it on the side of the national road. , On the one hand, it shows good luck, and at the same time, it also shows that there are really many wild animals in Tibet.

东达山对于游客而言，只是一个途径的免费景点，但站在观景台上，看着无处起伏的雪山，除了感受到它的气势磅礴之外，也可以想象当初人民子弟兵修建这条天路时的情景，我们只是在上面走走路都觉得累，他们却要在海拔5000多米的高海拔、没有公路的条件下修建一条人间天路，条件是何等的艰难，场面是如何的壮观。
