Which station in Guilin is the one from where is leaving bus to zhangjiajie? Is it direct bus?

I remember there was only one direct bus from GL to Zhangjiajie when I went there in 2010, leaving from local General Bus Station, but I forget the timetable. You can go there for consultation.

If it has been out of service, you can go to local General Bus Station to take a long-distance to Changsha and there are two buses, at 08:00 and 15:30. Upon arrival at Changsha, it will be easy to travel to Zhangjiajie, by bus or train.
