Hi. Wondering what train to take from Shanghai to Longyou to see the caves?

You can take a bullet train to Quzhou from Hongqiao Railway Station (about 2.5 hours). Then, take a bus to Longyou from the nearby Quzhou Passenger Transport Center. The buses are available from 6:40 to 18:00, and the fare is CNY 12. Upon arrival, take a bus to the caves.

The caves are open from 8:00 to 16:30. The admission fee is CNY 65 by the way. :)
