Fortunately for tourists, many of Rome's main attractions are concentrated in the centro storico (historic center) and can be covered on foot. Some sights that lie nearer the border of this quarter can be reached via the Metro Line A, nicknamed the linea turistica (tourist line) and include: the Spanish Steps (Spagna stop), the Trevi Fountain (Barberini stop), St. Peter's Square (Ottaviano stop), and the Vatican Museums (Cipro-Musei Vaticani stop), to name a few.
Tickets for the bus and metro can be purchased for EUR 1 at any tabacchi (tobacco shop) and at most newsstands. These tickets are good for approximately 75 minutes on buses, or a single metro ride. Day passes can be purchased for EUR 4, and weekly passes, which allow unlimited use of both buses and the metro, for EUR 16.
For a better explanation of the metro routes, pick up a free map from one of the tourist information booths scattered around the city: Tech-savvy tourists can navigate their way around Rome by accessing the web site of the ATAC (Rome's public transportation system), www.atac.roma.it.
