We travel by cruise from chongqing reach yichang 12pm,we planning to go wudangshan the same day. how?

From Yichang, you can only reach Shiyan instead of Wudangshan.
There are two buses from Yichang Bus Station to Shiyan, one at 08:00 in the morning and the other at 18:00.
It takes about four to five hours to reach Shiyan. Then you can sleep one night in Shiyan and then catch the earliest bus from Shiyan to Wudangshan.
