Ticket may be purchased in Barcelona automatic vending machines (at each TRAM stop) and also from other public transportation operators as well as at tobacco stores, newstands, lottery dealers and La Caixa branches.
You can use single tickets, valid only for the TRAM system, or integrated travel cards.
These integrated travel cards allow up to three transfers between TRAM, bus and metro during a single journey in zone 1 (Barcelona City) within a maximum of an hour and 15 minutes. The maximum time for transfers is increased by 15 minutes for each additional zone.
If you are going to use the public transport more than 4 times we recommend you to buy an integrated travel card T-10 valid for 10 journeys with transfers between bus, metro and tram (9,95€).
