Border Crossings
There is one gateway from Mainland China to the Macao Peninsula. The Barrier Gate in northern Macao operates from 7:00 AM to midnight. Proceed south to get intoCotai.
Macau’s second gateway will get you directly into Cotai. The Cotai Frontier Post at the Taipa-Coloane Reclaimed Area operates from 8:00 AM to 8:00 PM.
By Car
You can enter by road from Gongbei, Zhuhai if your vehicle (cars only, no motorcycles) has both Macau and China number plates and the driver carries both Macau and China driver’s licenses. Note that you have to switch sides of the road; China drives on the right, Macau on the left
By Bus
You can take the coach from Guangzhou. The trip takes you about 2 hours and costs around RMB70.
There is a direct coach from Shenzhen airport and also Shenzhen long distance bus station. The journey time form Shenzhen is about 3 hours.
You can also get a bus from either place to Gongbei bus station in Zhuhai. That puts you right across the street from the border facilities so you can walk to Macau (see next section). This can save you a bit of money; the bus is about the same price either way, but food and hotels are cheaper in Zhuhai.
