Barcelona Metro L7 was built when Barcelona City Council decided to extend Carrer Balmes beyond Traveserra de Gràcia and is consequently known as the Línea de Balmes.
A great deal of work was involved in building the tunnels and the line finally opened in 1929.
It runs from the the Plaça Catalunya to uptown Avinguda Tibidabo and is operated by Ferrocarrils de la Generalitat de Catalunya (FGC).
Given this is just a short line all the stops are important as they take you from Barcelona city centre to the Zona Alta of Sarrià-Sant Gervasi, traditionally the richest and most select part of Barcelona along with Pedralbes.
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.
