Witch bus can I take the best to Emei Shan to Chengdu

From Xinnanmen Bus Station, there are buses to the Emeishan directly. You can take one.

From the mountain, there is no bus to the airport. You need to take a bus back to Xinnanmen bus Station. Then take a taxi to Minshan hotel at a cost of CNY10, where you can take the airport shuttle bus line 1 to the airport.
