I'm planning to be in Jiuzhaigou in 13/9, while the vacation starts in 15/9.

Well, as I know, there will be crowded people during the Mid-autum Festival. The situation before that time would be better. However, you will still advised to go to the scenic area early and start to tour around. Have a nice journey!

I understand. In regards to the holidays, do you know if there is any possible time to travel from one place to another during the golden weekend of october? I'm planning to travel from deqin to lugu hu and I know I have to pass threw lijiang which is really crowded. Are there any quiet days during these week which make it possible? I'm not planning to travel in lijiang, only move threw it and stay there for one night. I heard then deqin and lugu supposed to be quiet, is that right? Thank you very much!

Well, you are advised to make it on October 6th or 7th, when there might be less tourists.

Yes, Deqin and Lugu Lake will not be as crowded as Lijiang. May you have a wonderful trip!
