Barcelona Metro L4 is one of the city centre's most used underground railway lines and opened in 1973.
It currently runs from Trinitat Nova to La Pau but is planned to be extended to the new railway station at La Sagrera|Meridiana.
Important Yellow Line stops in the city centre include Verdaguer, Passeig de Gràcia and Jaume I - the main stop for the Barri Gòtic.
The L4 Metro Line is also very popular in summer as it is the city beach line stopping at La Barceloneta, Poblenou, El Maresme|Fòrum and Besòs Mar.
You can buy single journey tickets and a variety of travel cards, including the excellent value T10, in the machines in the FGC entrances.
However, if you are visiting for a few days, it is well-worth investing in a Barcelona Card, which not only gives you full access to the Barcelona integrated transport system, including metro, buses, trams, ferrocarrils but also discounts on Barcelona museums and tourist sights as well as in some shops and restaurants.
