Hello Me and My freind want to visit zhangjiajie on 12th and 13 Sep 2015. Please guide us how we can

From Guangzhou Railway Station, there are three trains available to Zhangjiajie at 13:16, 15:39 and 21:35. The travel time is about 14 – 17 hours. Or you can also take a direct flight to Zhangjiejie.

Well, the Wulingyuan Scenic area is the highlight for sightseeing in that city, and it also includes hot spots like national forest park, Suoxiyu, Tianzi Mountain, Yuanjiajie.
For your sightsseeing, I suggest buy the tickets at CNY245, which is valid for four days. With that, you can visit all the spots above, and it also includes the sightseeing bus.

As for hotels, I suggest you live in Wulingyua Scenic area. There are many hotels in different standards available especially near Suoxiyu and Dongjiayu, Zixiaguan are and Wuling Road. You can have easy access to them.
