How many routes do they offer from chengdu to daocheng using local bus(north/ south line)?

1. There are two routes from Chengdu to Daocheng.
North route: Chengdu - Siguaniang Mountain- Xiaojin - Danba- Yajang - Litang - Daocheng
South route: Chengdu - Ya'an - Erlang Mountain - Luding - Kangding - Yajiang - Litang - Daocheng
And Daocheng is 100km or a little farther from Yading.

2. Generally speaking, eight days are enough to cover Jiuzhaigou and Daocheng Yading. Don't worry!
