Getting around Macau
Macau Being small, a good part of the old town can be visited on foot, especially centered around the square locally called "largo do senate" There is otherwise a rather efficient bus network, navigating between each island.
And if that is already quite sufficient, Macau still plans to build a metro network, the first line of which (Phase 1) expected to open in 2019. As it is small, it is also possible, if the weather is good, to rent a bicycle or even tricycles to travel around the islands.
See more on the site of Macau Tourism Office for more information.
Road transport
The buses : The bus network is well developed and practical for covering longer distances. This is the option we took to visit Coloane and Taipa. It's not expensive, 6 MOP per trip, and not too badly indicated. The only downside is knowing your direction of travel on the bus. Since the latter have loop circuits, it happens that they pass at the same stop but have an opposite final direction. We got caught out once or twice because of this...
To find out which bus numbers to take in advance, you can use the official site. Otherwise the directions are quite detailed at the bus stops.

Note that there is also a pass system, the MACAUpass. It is an electronic payment system installed in all public transport vehicles of Macau. Passengers then do not need change. The pass can also be used to make purchases in local shops and in certain bakeries that accept this method of payment, and can also be used at vending machines.
The pass remains practical in the sense that you have to pay the exact amount when you pay for the bus and the bus does not give change. (box system where you throw money into a box, the driver only validates the payment but is not intended to give change). In addition, each trip is cheaper since instead of 6 MOP you will pay 3 MOP if it is a normal bus and 4 MOP if it is an express bus.
If you are going directly from the airport to one of the big casinos (The Venetian, Wynn Hotel, City Of Dream) they have their own free shuttle bus.
There is also a hop on hop off bus system with a HK$125 per day pass that you can book here via Klook: Macau Open Top Bus Tour
In summary, to help you:
- Download the application Macau Bus Guide & Offline Map, on Android or MacauMap for iOS. Practical for finding your bus and your route thanks to the map accessible without internet.
- You can also simply use Google Maps to locate the nearest bus stop. and the bus line should be displayed by clicking on the stop icon then on the line number.
- The MacauPass allows discounts on every journey, to be validated on each journey via the appropriate terminal on the bus.
- If you pay in cash, have the exact amount ready. The operating policy of the buses is "NO EXCHANGE". To pay in cash, throw the coins in the box next to the driver's seat (at least it is rounded to 6 MOP, before it was 4.2 MOP)
- Boarding is always done in front, getting off is done through the back door.

Taxis : on only tested the taxi once to make it easier to get to Macau, between the ferry terminal and our hotel, a journey of just 3,5 km. Which cost us 41 MOP. The calculation being a support of 19 MOP then 2 MOP all 240 m. Finally, something new for us, a supplement is payable for any baggage placed in the trunk, 3 MOP by suitcase (or bag whatever).
Another peculiarity is that there is a surcharge of 5 MOP if you are arriving from the international airport of Macau (whatever your destination). The same surcharge applies from a pick-up to rammed earth Ferry Terminal, the campus of theUniversity of Macau, the border crossing at Hong Kong-Zhuhai-Macao Bridge Frontier Post or any journey between Macau et Columns.
Finally, for the journeys of rammed earth toward Columns, a small surcharge of 2 MOP applies. No surcharge on the other hand, if you go from Macau toward rammed earth or in the sense Taipa/Coloane towards the peninsula of Macau.
Rail transport
A light rail transit system called LTR is under construction in Macau. The first The line to be opened is to connect the Macau peninsula from Barra Square, next to the A-Ma Temple, passing through Taipa to the west, running along the main road of Cotai where casinos like the Venetian are located, and the terminus will be at Macau International Airport.

The future metro plan in Macau.
In the meantime, the only train available is not in Macau itself but the nearby Chinese city of Zuhai.
Shipping
There are 2 ferry terminals in Macau. One is on the peninsula, to the north, so closer to the old town: Macau Outer Harbor Ferry Terminal. This is the terminal through which we arrived from Hong Kong. This means that it is an "international" terminal and allows you to enter/exit Macau by going through immigration.
With the same functionality and also serving Hong Kong, there is a second terminal north of Taipa, Macau Taipa Ferry Terminal (sometimes called Cotai terminal). This one is attached to the international airport, so closer to the big hotels and casinos.

There are 2 main companies making round trips to Hong Kong:
In both cases, the fare will be HK$2 in the Hong Kong – Macau direction and HK$171 in the other direction Macau – Hong Kong, in economy class.
During our trip from Hong Kong to Macau, we chose Turbo Jet since no one was queuing in front and it was on sale at HK$150.

Nobody is queuing…
