need to get from HKIA to Guangzhou city. ETA at HKG is 09:25 hrs. looking for fastest way

Ferry is the fatest way and it leaves from HKIA to Guangzhou Nansha around 11:15. However, it is only in service on every Thursday and Saturday.

It is hard to take a taxi to Guangzhou. If you are lucky to get one, it is pricey.

No, the Airport Express can only take you to Tsing Yi, Kowloon and HK Stations, but the through trains for Guangzhou are from Hung Hom. You can take free shuttle bus at Kowloon to Hung Hom for the train. Except the train, direct buses can be taken at HKIA to Guangzhou. Many buses are arranged from 07:00 to 22:15 every day and it takes 3.5-4h.
