Travel from Airport to CUHK

1. Taking the taxi

One simple and fast but somewhat expensive way to get to CUHK is to take a taxi from the airport. Take a green-colored cab, not a red-colored one: those are cheaper.  The ride to CUHK campus should cost you HK$350 or so.  Be sure to use the addresses in Chinese given below, to advise the driver where you want to go

Conference Venue: 
AIT Building (School of Architecture),
The Chinese University of Hong Kong
Shatin, New Territories
沙田香港中文大學
崇基校園
綜合教學大樓 (建築學院)

2. Taking the MTR

You can take the MTR at the airport (i.e. Airport Station) and travel to the University Station. This costs HKD60 and takes about 65 minutes. Exit at Exit D to walk to the conference venue.

Octopus Card Service

If you want to be more adventurous in Hong Kong, it is recommended that you buy an Octopus Card for your own convenience. It can be used in most of the transportation, including buses (this includes A41), MTR, ferry, and some of the minibuses; it can also be used in most of the vending machines, convenient stores, and fast food shops. Octopus cards can be bought at the Customer Service Centres in the Airport Express Line and in all MTR stations (except Racecourse station). Ticket price for adults is HK$150 (with HK$50 of deposit which is refundable, and HK$100 of stored value). Some modes of transport give a slight discount to Octopus card users and having the card prevents you from worrying about always needing exact change.  It is very easy to use: simply swipe your card over the octopus machine, the fare will be automatically deducted, and its deducted values and remaining value will be shown on the screen of the machine.
