We are planning to get from Xiahe to Jiuzhaigou the day after tomorrow.

I was informed that I could travel from Xiahe to Hezuo and there transfer on to the Lanzhou Jiuzhaigou bus (departure time 09:00 from LZ). Does anybody know whether this is possible and in addition where does the LZ Jiuzhaigou bus stops in Hezuo? I read that this bus has three stops, Hezuo Langmusi Highway junction and Chuanzhusi.

In addition, how do I know for sure that we can take this bus?

Regards,
