From Macau Ferry to go and Coloane Island and Senado Square

Well, one day is enough to cover both of the two places. From the ferry terminal, you can take bus no. 3, 3A or 10A to Avenida de Almeida Ribeiro. Then you can walk to the Senado Square according to the signages. After visiting that, walk back to Avenida de Almeida Ribeiro to take bus no. 26A to Hac Sa Beach, which is right in the Coloane Island.

Ok thanks so much! Then what about from the Coloane Island back to Ferry Terminal? How long will it take roughly as i wouldn't want to miss my ferry if i have bought the ferry ticket.

As I have no idea where you are going to visit at the Coloane Island, it is hard to tell the exact way back to the ferry terminal. If you don't mind, I suggest you fully enjoy yourself there and then take a taxi to reach the ferry terminal in case.
