What is best way to go see Glass Bridge Zhangjiajie from Chengdu? And how about the return way?

You can take a direct flight from Chengdu to Zhangjiajie. But it is not available every day. Please check the schedule in advance.

Or, you can take a flight from Chengdu to Changsha first. And then transfer to a plane to Zhangjiajie Hehua Airport. Upon arrival, you may take a taxi to go directly to the scenic area.

After the tour, you may reverse the trip back to Chengdu.
