how do i get to west lake from hangzhou railway station? i'm taking the train down from shanghai.Thx

If you take the G-trains, you will reach the Railway Station, then you can take bus K7 to reach the Shaoniangong Bus Stop. Getting off the bus, you can see the lake. Or you can take a taxi to reach directly, which will cost you about 12 RMB.
If you take the D-trains, you probably will reach the South Railway Station, so you can take Bus No. 300 to reach the Railway Station then you can take taxi or Bus K7 to reach.
Hope it is helpful.
