From Zhangjiajie to Zhangye

From ZJJ to Zhangye, there is no direct transport. It is suggested to transfer at Changsha, which can be reached by taking a direct bus. Then you can take a direct train, the only train between, at Changsha Train Station to Zhangye within around 29h. It may be a hard journey.

To avoid the long term train journey, you can also travel in this way: Take a bus to Changsha and at the local airport to take a flight to Lanzhou. Then a direct train from lanzhou can take you to Zhangye within around 5.5h.

Thank you! And how long time I need to see Danxia Landscape? One day? Half a day? Can I see it and Mati Si during one day? (Asking because don`t have a lot of time for trip)

Half day is enough for the Danxia.
If you want to finish visiting the two places in one day, it is suggested to hire a car.
