Porto's Metro is one of the most recent in Europe, it has 6 lines and 81 stations.
With the passage of time, trams (3 lines) in Porto have become a popular tourist attraction more than a means of transport, especially with the arrival of the underground system, buses and regional trains.
Although the local buses in Porto are sometimes the only means of transport to get to certain destinations, they make for the least appealing public transport in the city.
The most useful routes to get to Gaia from Porto city centre are: 900, 901 and 906, which depart from Trinidade or 904 that leaves from Batalha and Praça de Liberdade.
