Leaving Barcelona on public transport
You can also use Barcelona's public transport system to get out of the city: the metro, the trams, the buses and the trains all have lines that go beyond the city boundaries and reach neighbouring towns in Baix Llobregat, El Barcelonès and El Vallès. However, in this case there is a supplementary charge, as you enter new fare zones. You can either buy a single ticket or go for a multi-journey travelcard.
If you are only visiting the city for a few days, there are different types of travelcards you can buy in order to save money on public transport. The T10 card gives you ten journeys, combining different means of transport, but there are also day travelcards on offer. TMB's Hola BCN! card which is for a single person, allows unlimited journeys for a fixed fare: there are cards for two, three, four and five-day periods.
Use public transport without getting lost
Barcelona's public transport network is very user-friendly: every train and metro station has maps showing their location, and on board the trains there are luminous panels showing the line's route. When travelling by bus, there is information about the different lines, including times, direction and bus stops, at each bus shelter. It is important to know that Barcelona residents use four basic orientation points for the city: seawards (east) and mountainwards (west), the Besòs (north) and the Llobregat (south).
