I want to go to jiuzhaigou (juzhai valley) from Guilin ...can you suggest best way to travel ?

Well, it is best to fly to Chengdu first within 2h. Then transfer to another flight to the Jiuhuang Airport in an hour. After that, take a shuttle bus or take a taxi to the valley. Or upon getting to Chengdu, go to the Xinnanmen or Chadianzi Bus Station, take a long-distance bus to the valley directly in 8-9h.
