Rome's metro system is modest for a capital city — three lines, 73 stations, and a Line C that has been under construction since 2007. This is the honest guide to what works, what doesn't, and how to use it.
Plan my Italy trip →Rome has three metro lines. Line A covers the main tourist corridor: Vatican, Spanish Steps, Trevi Fountain area, and Termini. Line B connects Termini to the Colosseum in 8 minutes. Line C is a partially functioning modern line that has been under construction since 2007 and may reach the Colosseum by the time a child born today finishes university. This is what you need to know.
Line A (orange): The tourist line. Runs from Battistini in the west to Anagnina in the southeast, passing through: Ottaviano (Vatican Museums/St. Peter's, 10-minute walk), Lepanto (Prati neighborhood), Flaminio (Piazza del Popolo, Villa Borghese), Spagna (Spanish Steps, Trevi Fountain 15-minute walk), Barberini (Trevi Fountain 5-minute walk), Repubblica, Termini (interchange with B), San Giovanni. Hours: Mon-Thu and Sun 5:30am-11:30pm; Fri-Sat until 1:30am. Line B (blue): The Colosseum line. Runs from Laurentina in the south to Jonio in the northeast, passing through: EUR (Mussolini's model city), Piramide (Testaccio, Ostiense), Circo Massimo, Colosseo (Colosseum entrance adjacent), Termini (interchange with A), Tiburtina. Line B1 branches from Bologna to Jonio. Line C (green): Currently runs from Pantano to San Giovanni (interchange with A). Limited tourist utility. Future extension toward the Colosseum via Venezia is planned but delayed repeatedly — as of 2026, no confirmed opening date for the central extension.
A single BIT ticket costs €1.50 and is valid for 100 minutes from first validation — covers unlimited buses and trams plus one metro journey. The 24-hour BIG pass costs €7; 48h costs €12.50; 72h costs €18; weekly CIS costs €24. Tickets are sold at tabacchi (orange "T" signs), newsstands, metro station vending machines, and the MooneyGo app. Buy before entering — there's no on-board purchase. Validate in the orange machine at the turnstile (metro) or on the bus/tram. Fine for unvalidated ticket: €54.90. The Roma Pass (€28 for 48h or €38.50 for 72h) includes free museum entry (Colosseum, etc.) plus unlimited transport — see the Roma Pass guide for whether it's worth it for your itinerary.
Rome's first metro line (Line A) opened in 1955 — a decade after Milan's first line. The delay and the subsequent slow expansion tell the same story: every significant excavation in Rome's center breaks through into something archaeologically significant. The construction of Line A in the 1950s was relatively straightforward because it followed routes where the archaeological density was lower. Line B (1990) encountered more issues. Line C, running through the historic center from San Giovanni toward Venezia, has been the most archaeologically disrupted metro construction in history — a massive station complex at Piazza Venezia was designed but found impossible to excavate because the site contains continuous Roman archaeological material from the Republican through Imperial periods. The entire station project was redesigned three times. As of 2026, the central section (Venezia → Colosseo extension) has an estimated completion of 2030 at the earliest, and that estimate has been revised upward four times since 2010.
Metro Line B from Termini to Colosseo: 3 stops, approximately 8 minutes. The Colosseum entrance is literally adjacent to the Colosseo metro exit — walk up the stairs and you're looking at it. This is the single most useful journey in the Rome metro for tourists. Book Colosseum tickets in advance at coopculture.it (€18-20, timed entry) — with a booked ticket you skip the walk-up queue which can be 90 minutes in summer. Taking Line B from Termini also serves: Circo Massimo (one stop before Colosseo, for the Circus Maximus and Aventino hill access) and Piramide (two stops after Colosseo, for the Pyramid of Cestius, the Protestant Cemetery with Keats and Shelley's graves, and the Ostiense nightlife area).
Generally yes, with specific caveats. Line A between Termini and Spagna is the highest-pickpocket-density stretch of any Rome metro line — the combination of high tourist traffic, crowded carriages, and multiple stops makes it attractive for distraction theft. Keep bags in front with zips facing you, phone not visible, on this specific section. Late-night Line A on Friday and Saturday (running until 1:30am) carries entertainment-district crowds — lively and occasionally loud, not dangerous. Line B is somewhat calmer. The Termini interchange area (where A and B meet) is the highest-risk single location in the entire network — standard caution applies at all hours. The Colosseo stop on Line B is well-monitored with frequent police presence due to the adjacent tourist site.
Trastevere is not served by any metro line. The Trastevere rail station (on the FR3 regional line, not the metro) is on the western edge of the neighborhood but is primarily a suburban commuter stop rather than a tourist resource. The practical solutions for reaching Trastevere: Tram 8 from Largo Argentina (8-10 minutes, the best option from the historic center), Bus H from Termini (25 minutes), walking from Campo de' Fiori area across the river (10-15 minutes). The absence of metro access is partly historical (the Trastevere medieval street grid is too narrow for a metro station entrance) and partly a consequence of Rome's overall metro under-development relative to its size.
Standard hours: Monday-Thursday and Sunday 5:30am to 11:30pm. Friday and Saturday: 5:30am to 1:30am (the extended weekend service is significant for nightlife). There is no 24-hour metro service. Between approximately midnight and 5:30am on weekdays, night buses (ATAC notturno services, marked with N prefix) replace the metro on main corridors. For late-night returns from restaurants or nightclubs on a Tuesday or Wednesday: plan around the last metro departure from your starting point — posted at each station and available on the Moovit app. Taxis are metered and available throughout the night; the night surcharge applies after 10pm.
Colosseo (Line B): Exit directly at the Colosseum entrance — walk up the stairs and you're looking at it. Also serves the Roman Forum and Palatine Hill (5-minute walk along Via Sacra). Circo Massimo (Line B): The Circus Maximus, Aventino hill (Orange Garden with keyhole view of St. Peter's Dome), and Testaccio food market. Spagna (Line A): Spanish Steps, Keats-Shelley House, Trinità dei Monti church, start of the Borghese Gallery walk uphill. Ottaviano (Line A): Vatican Museums and St. Peter's Basilica (5-10 minute walk south through Prati). Flaminio (Line A): Piazza del Popolo, Villa Borghese park, MAXXI contemporary art museum (15-minute walk along the river), start of Via del Corso.
The BIT (Biglietto Integrato a Tempo) at €1.50 covers 100 minutes of unlimited trams and buses plus one metro ride. The 24h BIG pass (€7) covers unlimited everything including unlimited metro rides. The Roma Pass (€28/48h or €38.50/72h) includes unlimited transport AND free entry to the first 1-2 museums visited (Colosseum, Borghese Gallery, and others) plus discounts on subsequent entries. The Roma Pass makes sense if you're visiting 2+ paid attractions that are included in the pass — the Colosseum alone costs €18-20, which more than pays for the transport component. If you're only doing transport (no major paid attractions or already have museum bookings), stick with the BIG daily pass at €7.
Line C delays are the result of a combination of factors: the archaeological complexity of the historic center (every excavation site finds Roman-era material requiring documentation and often redesign), contractor issues including the bankruptcy of the original main contractor in 2013, and the funding limitations of Rome's chronically underfunded capital administration. As of 2026, Line C operates from Pantano to San Giovanni (interchange with Line A). The extension to Piazza Venezia (passing under the Imperial Fora and the Colosseum area) has been planned, funded, re-planned, and re-funded multiple times. The Piazza Venezia station is the most archaeologically complex station ever attempted — designs have been revised repeatedly as excavation reveals new material. Current optimistic projections suggest the Venezia station by 2030; previous projections (2015, 2018, 2022) proved wrong.
Every Italian site that is worth visiting has an advance booking option that eliminates or dramatically reduces queuing. The Vatican Museums require advance online booking at tickets.museivaticani.va (book 2-4 weeks ahead in spring/summer). The Colosseum requires booking at coopculture.it. The Last Supper in Milan requires booking 2-3 months ahead at cenacolovinciano.vivaticket.it. The Leaning Tower of Pisa requires booking at opapisa.it. The Borghese Gallery in Rome requires booking. Every timed-entry museum in Italy is better with advance booking. Italy's greatest experiences reward people who plan: an unbooked visitor and a booked visitor arrive at the same site and have completely different experiences purely based on whether they spent 3 minutes on a website before leaving home.
A handful of phrases solve most practical travel situations: "Un biglietto per [destination], per favore" (one ticket to [X], please). "È valido questo biglietto?" (is this ticket valid?). "Dov'è la fermata del [vaporetto/autobus/metro]?" (where is the [vaporetto/bus/metro] stop?). "C'è uno sciopero?" (is there a strike?). "Quanto costa?" (how much does it cost?). "A che ora parte?" (what time does it leave?). Italian transport staff in tourist areas will generally switch to English if you've made a genuine attempt at Italian first — the attempt at Italian signals respect, and the switch to English usually follows immediately.
They understand that Italy's best experiences require either early timing or advance booking — rarely both. The Vatican Museums at opening time (9am sharp) are a different experience from the Vatican at noon: the Sistine Chapel has 200 people vs 2,000. The Leaning Tower of Pisa at 9am has the Piazza dei Miracoli largely to yourself; at 11am the coaches have arrived. The Last Supper is always timed-entry so the experience is consistent — but getting the slot in the first place requires booking months ahead. The pattern across Italy is identical: the best version of any famous site is available, but requires planning. The improvised version (arrive and see what happens) works for low-season travel but fails in summer for anything that requires a ticket.
Almost always: the thing that isn't in the guidebook's top 5. Near the Vatican Museums: Castel Sant'Angelo (the Mausoleum of Hadrian converted into a papal fortress — extraordinary views of Rome and the connecting passetto corridor to the Vatican, €15). Near Florence's airport: Fiesole (30 min by Bus 7 from Piazza San Marco — Roman theatre, Etruscan walls, views of Florence, and almost no tourist crowds on a weekday). Near Bergamo airport: Bergamo Alta itself (walk the Venetian walls at sunset, find a restaurant away from the tourist main square, drink the local Valcalepio wine). Near the Leaning Tower: the Camposanto's Triumph of Death fresco — one of the most important medieval paintings in Italy, in a building that most Pisa visitors don't know exists.
