OTS WHERE Zhangjiajie National Park The ‘Avatar’ Mountains WHEN Beautiful with every season although the steep walkways would be treacherous in Winter! HOW Bus from Zhangjiajie city... only about 40 minutes and 25RMB. Entrace fee is 245RMB however, there is a hostel actually in the park. You can stay there and explore properly...there is NO way you could see all of the park in just one day. WHY Because these are the mountains that James Cameron based his Avatar ‘Hallelujah’ Mountains on. Make sure you also check out the Bailong elevator.
