Getting to Barcelona – By Plane

Barcelona-El Prat airport is located in El Prat de Llobregat just 12 km South West of the Barcelona city centre. It has two passenger terminals: Terminal 1 (T1) and Terminal 2 (T2). The airport has allocated airlines to terminals, regardless of the destination of the flight.

Airport Transfers to the city centre

The Aerobús is an express bus service that connects the Barcelona-El Prat airport with the city centre (Plaça Catalunya) in 35 minutes. You can take the Aerobús outside Terminal 1 (A1) and Terminal 2 (A2). This service runs every day of the year with departures between 5 and 15 minutes. From the city centre, you can take the metro or a bus to move around Barcelona.

The train service (R2 line) runs approximately every 30 minutes to and from Barcelona airport to the city centre. The journey takes 25 minutes. The train service operates from Terminal 2 (T2). To get from T2 to T1, use the shuttle bus service (Bus transit T1-T2). If you travel from the airport to the city centre, you can get off at Barcelona-Sants, Passeig de Gràcia or Clot which are serviced by metro stops.

You can also take the metro line L9 (orange) from the airport. It departs at Terminal 1 and connects at stations Torrassa (L1 and L10 Sud), Collblanc (L5 and L10 Sud) with metros to the city centre. 

You will find a taxi rank outside any of the main terminal exits. Look for the sign pointing to the nearest taxi rank. All official Barcelona taxis are black and yellow and are required to charge you only the value on the taximeter (plus any surcharge, e.g. luggage or night). The rates and surcharges are displayed inside the cab. In Barcelona, a taxi may be either ordered by phone, found at authorised taxi rank or flagged down in the street.            

Getting to Barcelona – By train

Barcelona Sants is the main train station for national and international arrivals and departures in Barcelona. It is situated in plaça dels Països Catalanes – Barcelona. National and regional trains also depart from França station. It is located at avinguda Marquès de l’Argentera, s/n – Barcelona.

Spanish Railways (RENFE)

Public Transport in Barcelona

Metro and tram

The metro network of Barcelona is very good and the trains are frequent and quick. You do not have to worry about timetables. Almost all attractions are within walking distance of a metro or tram station. When there are no subways, the gap can be filled by tram.

You can find the operating hours of the metro and tram here.

Buses

The operating times of the buses are different for each line. You will find a notice board with the timetable at each stop. They operate from about 5:00 clock to about 22:00 clock.

Night bus (NitBus)

Both the metro and the buses do not run all night. In Barcelona, there is a fairly dense network of night buses to get you back to your hotel all night long. Except for the line N0 all lines stop at Plaça Catalunya and can change there. The N0 line is a circular line that allows you to circle around the city center and change to the other NitBus. The night buses are operated by the private operator AMB, which is why the Barcelona Card and Hola BCN Ticket are not valid.

The N17 line goes to the airport.

The operating hours of the NitBus are different for each line, but they run from about 22:00 to 05:00 clock.
