How easy is it to get from Hengyang to Zhangjiajie Grand Canyon, the glass bridge in particular?

U are suggested to take a train from Henyang to ZJJ. Upon getting off, walk to ZJJ Central Bus Station. You can take a bus to Wulingyuan Scenic Area, where there are direct buses to the Grand Canyon.

The train journey takes 8-9h. Buses to Wulingyuan take around 50min and it costs CNY12. And the duration to the canyon is 40min or so and the fare is CNY15. Hope you can refer to the info to allocate your time.
