The metro can take you to many places. A one-journey ticket cost €1.50, so it’s probably best to buy a multiperson 10-ride ticket for €6.90 (called a T-10) or a personal 50-ride monthly ticket for €27.55. These tickets are also valid on the buses and trams. . 1- to 5-day public transport tickets are available which allow unlimited travel on the metro and bus networks (€9.6 for two days). These are excellent value. Be sure to look after them well as bent or damaged cards will not be read by the ticket machines (such cards can be replaced at one of TMB’s customer service centers).
We recommend you purchase the Barcelona Card in advance, which features unlimited free travel on public transport and free admission and discounts at around 100 visitor attractions. The card is available for purchase for periods of between 2 and 5 days, costing €24 for a 2-day card and €34 for a 5-day card.
