Hi, Samiel,
Greetings!
Many thanks for questions.
At first, it is a pity to let you know that there isn’t direct train from Xian. You will need to take train from Xian to Changsha ( capital of Hunan Province), then change train from Changsha to Zhangjiajie.
There are many high speed train from Xian and have a stop in Xian as below. You could choose a suitable one according to your tour schedule.
G820/G817 0802/1416 Xian North Station-Changsha South Station
G824/G821 1049/1656 Xian North Station-Changsha South Station
G838/G835 1223/1837 Xian North Station-Changsha South Station
When you arrive at Changsha South Station. You might need to take taxi or local bus to Changsha Railway station where you could find train to Zhangjiajie.
There is a suitable overnight train, starting from Zhangjiajie and ending at Zhangjiajie as below,
K9031/K9034 2030/0745+1 Changsha Railway Station-Zhangjiajie Railway Station.
In this case, you could have time to visit Mt. Tianmenshan (Heaven Gate) before going to Wulingyuan Scenic Area.
Regarding to the bus, we do not suggest as it takes more than 15 hours from Xian to Zhangjiajie and there aren’t many choice. Besides, the condition is also not good.
The fastest way is by air. There is 1-2 night flights from Xian to Zhangjiajie, but it is seasonable. It depends on when you take the tour. If it is at low season, the flight is not available.
