Is there a direct bus from Diebu to Jiuzhaigou? , or transfer from anywhere. . If you can walk, how is the road condition?

Self-driving or chartered cars are more reliable. Diebu to Jiuzhaigou = Gannan to North Sichuan, passing through three counties of Diebu, Ruoergai and Songpan, passenger transportation will cost you money

If there is no through train, you can go to Langmusi first, then from Langmusi to Ruoergai, then to Chuanzhu Temple or Songpan, and finally to Jiuzhaigou.

There should be a car from Diebu to Jiuzhaigou, and it was not far in the past. There are mountains there, and the road conditions are okay now, because the weather of heavy rain has passed.
