Being such a tiny place, you'll have little difficulty getting around Macau. Many, if not all, places can be reached on foot. And if you get tired, try the cheap taxis , bearing in mind that trips to Taipa or Coloane will attract a surcharge on top of the meter reading of 5ptca from Macau, and 2ptca between the two islands. Otherwise, hop onto one of the many buses - some important bus interchanges include the Jetfoil Terminal (referred to as Nova Terminal), the Hotel Lisboa, Almeida Ribeiro, Barra (near the A-Ma Temple), Praça Ponte e Horta (near the Guangzhou Ferry Pier on the inner harbour), Barra (near the Maritime Museum on the inner harbour), the Barrier Gate (referred to as Porto do Cerco) and the islands Taipa and Coloane. As in Hong Kong, change is not given on buses, but fares are low. There are two main bus companies, and some useful routes include:

 

#3 and #3A from the Jetfoil Terminal to Hotel Lisboa and Almeida Ribeiro.

#5 from Barra to Almeida Ribeiro to the Barrier Gate.

#21 , #21A , #26A and #28A from Almeida Ribeiro to Taipa Village and Coloane.

#28B from the Jetfoil Terminal to Hotel Lisboa and Rua de Praia Grande.

Finally, cycling is a possibility, on the islands at least, though note that you are not allowed to cycle over the causeway from the mainland to Taipa.
