What is the travelling time from Changsha to Zhangjiajie. Is there any train available?

There are direct trains between them. It generally takes about 5~5.5 hours.

I notice you are from Singapore, me too. I just got back from there(ZJJ). I traveled from by flying to Guangzhou(Tiger Airlines), then took a night train from Guangzhou to ZJJ, 11 hours, get a sleeper, very comfortable. Get the ticket from Guangzhou Central Railway station, I believe cost 544 yuan.( The rate was revised 1 Jan 2013). Arrive ZJJ early morning.

Thank for sharing your information. Do you have any interesting places which we must visit. We are going to ZJJ in early March this year.
