how do i get from yichang dong railway station to jiuwanxi ?

At YC East Railway Station, you can take lcoal bus no. 9 to Mobile Communication Square (Yotong Tongxin Guangchang Station) to walk to Haitong Bus Station, where you can take a bus to Zigui. Upon your arrival Zigui, there are many direct buses to Jiuwanxi.

Well, the bus fare from YC to Zigui is CNY18 per person. And I remember the fare for the rafting is CNY180 per person.

To go back to YC, you can use the same way as coming.
