How to get to wuzhen scenic area from hangzhou xiaoshan airport

Well, there are many direct long-distance buses from the airport to Wuzhen Bus Station.
Then it is close to the scenic area: Dongzha and Xizha. You can even walk there directly.

where can i find more info on what are the buses available n where do i go to get the info?

The shuttle bus info can be found in the official website of the airport, but it only has Chinese version. I can tell you that the bus can be taken near gate no. 14, arrival level of the terminal building. Buses are scheduled from 09:30 to 21:10, 12 buses in total.
