bus from chengdu to huanglong jiuzhaigou and back to chengdu

Go to Chengdu Xinnanmen Bus Station to take a direct long-distance bus to JZG scenic area in 8-9h/. After visiting, two buses are scheduled to Huanglong, leaving at 07:00 and 07:30. If you miss that, it is best to rent a car or minivan to get there.

To go back to Chengdu from Huanglong, I suggest you rent a car or take a bus to Chuanzhusi first. There you can also have a short visit and then transfer to a bus to Chengdu.
