Public Transportation: Bus, Tram, and Metropolitana

Although most of Rome's sights are in a relatively circumscribed area, the city is too large to be seen solely on foot. Try to avoid rush hour when taking the Metro (subway) or a bus, as public transport can be extremely crowded. Mid-morning or midday through early afternoon tends to be less busy. Otherwise, it's best to take a taxi to the area you plan to visit if it is across town. You should always expect to do a lot of walking in Rome, especially considering how little ground the subway actually covers, so plan on wearing a pair of comfortable, sturdy shoes to cushion the impact of the sampietrini (cobblestones). You can get free city and transit maps at municipal information booths.

Rome's integrated transportation system includes buses and trams (ATAC), the Metropolitana (the subway, or Metro), suburban trains and buses (COTRAL), and commuter rail run by the state railway (Trenitalia). A ticket (BIT), valid for 100 minutes on any combination of buses and trams and one entrance to the Metro, costs €1.50. Tickets are sold at tobacco shops, newsstands, some coffee bars, automatic ticket machines in Metro stations, some bus stops, in machines on some buses, and at ATAC ticket booths. You can purchase individual tickets or buy in quantity. It's always a good idea to have a few tickets handy so you don't have to hunt for a vendor when you need one. All tickets must be validated by time-stamping in the yellow meter boxes aboard buses and in underground stations, immediately prior to boarding. Failure to validate your ticket will result in a fine of €54.90. You can now pay for fines on the ATAC website. Pay immediately, or the fine will increase to €104.90 if you pay after five days. You can also pay fines in post offices, authorized shops, or by wire transfer. Do not pay the ticket inspectors in cash; some may be equipped for payment by mobile POS.

A Roma24H ticket, or biglietto integrato giornaliero (integrated daily ticket), is valid for 24 hours (from the moment you stamp it) on all public transit and costs €7. You can also purchase a Roma48H (€12.50), a Roma72H (€18), and a CIS (Carta Integrata Settimanale), which is valid for one week (€24). Each option gives unlimited travel on ATAC buses, COTRAL urban bus services, trains for the Lido and Viterbo, and Metro. There's an ATAC kiosk at the bus terminal in front of Termini station. If you're going farther afield, or planning to spend more than a week in Rome, think about getting a BIRG (daily regional ticket) or a CIRS (weekly regional ticket) from the railway station. These give you unlimited travel on all state transport throughout the region of Lazio. This can take you as far as the Etruscan city of Tarquinia or medieval Viterbo.

The Metro is the easiest and fastest way to get around Rome. There are stops near most of the main tourist attractions; street entrances are marked with red "M" signs. The Metro has three lines: A and B, which intersect at Termini station, and also C. Linea A (red) runs from the eastern part of the city, with stops at San Giovanni in Laterano, Piazza Barberini, Piazza di Spagna, Piazzale Flaminio (Piazza del Popolo), and Ottaviano/San Pietro, near the Basilica di San Pietro and the Musei Vaticani. Linea B (blue) has stops near the Colosseum, the Circus Maximus, the Pyramid (Ostiense station and trains for Ostia Antica), and the Basilica di San Paolo Fuori le Mura. Linea C runs from the eastern outskirts of the city through Pigneto. The Metro opens at 5:30 am, and the last trains leave the last station at either end at 11:30 pm (on Friday and Saturday nights the last trains on the A and B lines leave at 1:30 am).

Although not as fast as the Metro, bus and tram travel is more scenic. With reserved bus lanes and numerous tram lines, surface transportation is surprisingly efficient, given the volume of Roman traffic. At peak times, however, buses can be very crowded. If the distance you have to travel is not too great, walking can be a more comfortable alternative. ATAC city buses are orange, gray-and-red, or blue-and-orange; trams are orange or green. Remember to board at the rear and to exit at the middle: some bus drivers may refuse to let you out the front door, leaving you to scramble through the crowd to exit the middle or rear doors. Don’t forget that you must buy your ticket before boarding, and be sure to stamp it in a machine as soon as you enter. The ticket is good for a transfer and one Metro trip within the next 100 minutes. Buses and trams run 5:30 am–midnight, after which time there's an extensive network of night buses with service throughout the city.

The bus system is a bit complicated to navigate due to the number of lines, but ATAC has a website ( that will help you calculate the number of stops and bus route needed, and even give you a map directing you to the appropriate stops. To navigate the site, look for the British flag in the upper right-hand corner to change the website into English.
