What is the best way to travel by bus from Jingzhou to Wulingyuan or Zhangjiajie ?

From Jingzhou, there is no direct bus or train to ZJJ.
if you want to take a bus, you need to take a bus for Wuhan in about 3.5 hours, then tran to Changsha in about 1.5 to 3.5 hours and the last for ZJJ in about four hours' bus journey.
If you travel with other people, it is suggested to hire a car together to go and in this way, it takes about four hours and thirty minutes.

We arrived easely from Jingzhou by bus to Zhanjiajie.
For this, we needed 2 buses:
1. Jingzhou to Changde, almost 4 hours, 4 buses in the morning.
2. Changde to ZJJ, 2 hours.
