In Braga, there is a bus network covering the entire city. Buses can be identified by their logo:
The most direct buses from the city centre to University of Minho and MELIÁ HOTEL and HOTEL DE LAMAÇÃES (the recommended ones for the conference) are BUS N. 43 (direction Universidade do Minho) and BUS N. 02 (direction Bom Jesus).
Alternatively, you can use a taxi. From the railway station to MELIÁ and LAMAÇÃES HOTELS it will cost you about 5 Euros. Portuguese taxis have a pale brown colour, but many keep the traditional colours, black and green.
