On your web mentioned that we can go to Huangshan from Hangzhou Xiaoshan International airport or City's tourist center. How?

As I know, there is only one bus from HZ Xiaoshan Bus Station and no buses from the airport to the Huangshan.
The only one bus from Xiaoshan Bus Station is at around 07:00.
Other buses are from HZ West Bus Station. To reach the West Bus Station, you need to take the airport shuttle bus to get to the railway station first and then take a taxi to reach. The West Bus Station is at No. 357, Tianmushan Road and about 38km from the airport.

As mentioned from Linda that there is one bus from Xiaoshan bus station to Huangshan is arround 07.00 morning. Would you please let me how to go to Xiaoshan bus station from Xiaoshan international airport? Just for info that we arrive Xiaoshan International airport from Guilin international airport. Thanks.

From the airport, there are direct buses for Xiaoshan long-distance bus station and the buses are at 07:20, 08:20, 09:40, 10:30, 11:20, 12:10, 13:00, 13:50, 14:40, 15:30, 16:20, 17:10, 18:00, 18:50 and 20:00.
