Is there trains to/from Harbin Airport?

Metro train is not available in the airport, but you can take shuttle bus to reach these destinations.
To Zhaolin Park and the hotel, you can take shuttle bus line 3 and get off at Central Avenue. Then it is within walking distance to both of them.

Back to the airport, walk to the south for about 1000 yards, take airport shuttle bus line 3 from no. 59, Jingwei 2nd Street.
