The city has a good public transport network that combines the bus, the Metro (subway), the TRAM (tramway) and the train, which reaches out the metropolitan area. The most convenient way of getting to the different parts of the city is the metro. The train frequency is very high, connections between the different lines are usually well indicated and it reaches most of the areas of interest in the city. The cost of tickets has been unified across the different public transport services. Details can be found at Transports Metropolitans de Barcelona (TMB).
Bus lines cover almost every part of the city, and there is also a tourist bus that takes the visitor along the main attractive sights of the city (Barcelona Bus Turístic, must purchase specific tickets). In addition to the metro and bus lines, the area of the conference venue is also served by the tramway [TRAM]. Details can be found at the TRAM website.
At night, taxis are a competitive choice.
