Hi I am planning to go to Macau from Guangzhou. What are the transportation option for the trip from Guanzhou to reach that city?

Both bus and express train is available.

By bus: you can take a direct bus at Guangzhou Provincial Bus Station to Zhuhai Gongbei Bus Station. Then you can easily walk to the immigration border to cross it to get into Macao.

By train: At Guangzhou South Train Station, take an express train to Zhuhai and you will arrive at Zhuhai Train Station near Gongbei border. Cross the border to walk to your destination.
