How long will be the journey from Hong Kong Airport to Chimelong Resort by train via Kowloon?

Take airport shuttle bus no. A21 to Hung Hom Station in around 70min. Then at Hung Hom Railway Station, you can take a train to GZ East Railway Station in around 2h. Then you need to transfer to local subway to your destination.

Actually, there are direct corss-border coaches at HKIA to Chimelong Hotel, GZ and the travel duration is around 3.5h. It is highly recommended to take that to the hotel first. Then you can take the hotel shuttle bus or walk to the resort.
