Bus from Changsha to Wulingyuan/Zhangjiajie

The bus station near the main railway station is called Changzhutan Bus Station. West Bus Station has 12 departures each day, while Changzhutan Bus Station has 10. But you are advised to take a bus to Zhangjiajie from Changzhutan Bus Station because it is more convenient for you. The buses are scheduled from 8:20 to 19:00 at an hourly interval. The fare is CNY 120. The trip takes about 4 hours. Upon arrival, take a bus to Wulingyuan for CNY 12 (about 50 minutes). :)

Thanks Lee for your prompt reply. Is there any bus from Changzhutan direct to Wuling Yuan bus station at Gui Hua Rd.? There are 4 of us catching the bus.
Any idea what time the bus ticketing counters are open in the morning for Changzhutan and West Bus Station?
To confirm the location of the Changzhutan bus station, is it located on the north of Wuyi Road and it is parallel road to Wuyi Road. Which is also on the opposite side of the Changsha Railway station?
To confirm the location of the West Bus Station, is it located south of Wangchengpo Metro station?
Thanks for your patience.

1. As I know, no direct long-distance bus from Changzhutan Bus Station to Wulingyuan Bus Station.
2. The opening hours of the ticket counter in Changzhutan Bus Station is 06:00 to 21:00, while West Bus Station is 06:00 to 21:30.
3. Yes, the detailed locations of two bus stations are correct. Don't worry.

Which exit should I take at Wangchengpo Metro Station in order to go to West Bus Station? Can I walk to the West Bus Station from Wangchengpo Metro Station and how long walking time? Thank you.

Take Exit B1 of Wangchengpo Metro Station. Then, walk south along Yulan Road for about 250 yards, and you can see the West Bus Station. You can walk there within 5 minutes.
