Rome’s public transport is cheap compared with many European capitals, but the ticket system causes more confusion than the price itself. The important things to understand are how long each ticket lasts, where you can use it, when it must be validated and whether buying a daily pass actually saves you money.
The standard ticket is the BIT, which costs €1.50 and is valid for 100 minutes from the first validation. During those 100 minutes you can use Rome’s buses and trams and make connections within the ticket rules. On the Metro, however, think of the BIT as one continuous Metro journey. You can change between Metro lines without leaving the controlled area, but once you exit through the turnstiles you cannot simply enter the Metro again with the same BIT because there are still minutes left on it.
For most visitors staying reasonably close to central Rome, this €1.50 ticket is all they need. The historic centre is much more walkable than it first appears, so a normal sightseeing day may involve one Metro ride in the morning, several hours on foot and another bus or Metro journey later in the day.
The current unlimited tourist tickets are €8.50 for 24 hours, €15 for 48 hours and €22 for 72 hours. There is also the CIS weekly ticket at €29. One important change from older Rome advice is that the 24-hour ticket does not expire at midnight. It is valid for a full 24 hours from the moment you first validate it. The 48-hour and 72-hour tickets work in the same way, starting from their first validation. The CIS works differently: it is valid through midnight on the seventh day, counting the day on which you first validate it.
That makes calculating whether a pass is worthwhile quite easy. Six separate BIT tickets cost €9, so if you genuinely expect to make six or more separate journeys during one 24-hour period, the €8.50 24-hour ticket starts to make sense. If you expect only two or three journeys, you would spend €3 or €4.50 with individual tickets and there is no reason to pay €8.50 simply because you are a tourist.
The same logic applies to the longer passes. Ten BIT tickets cost €15, exactly the price of the 48-hour ticket. Fourteen BIT tickets over three days cost €21, while the 72-hour pass costs €22. You therefore need to be using public transport quite regularly before these products produce a meaningful saving.
This is why we would plan the sightseeing first and buy the transport ticket second. If you group the Colosseum, Roman Forum and Capitoline area together, then visit Trevi, the Spanish Steps, Pantheon and Piazza Navona as another walking area, you may discover that you use public transport much less than expected.
Where to Buy Rome Public Transport Tickets
Rome public transport tickets are easy to find once you know where to look. You can buy them from ticket machines inside Metro stations, ATAC ticket offices, tobacconists, newsagents and other authorized sales points across the city. ATAC says there are around 2,200 authorized points of sale, so you usually do not need to go far to find one.
For most visitors, the easiest option is either a Metro ticket machine or Tap&Go with a contactless bank card, phone or smartwatch. If you prefer a paper ticket, tobacconists are particularly useful because they are everywhere in Rome and often sell BIT tickets as well as longer-duration transport passes.
Digital tickets are also available through supported apps, including services such as MooneyGo, TicketAppy, Tabnet and Trenitalia. If you buy a digital ticket, make sure you understand when and how it must be activated before starting the journey.
One practical tip is to buy a couple of BIT tickets in advance if you know you will need them later in the day. This is especially useful when you are away from a Metro station, because not every bus stop has a ticket machine and you should not assume you can always buy a paper ticket once you are already on board.
If you are using Tap&Go, you do not need to buy a ticket first. Just use the same contactless card or device consistently for your journeys so the system can calculate the correct fare.
Tap&Go is often the easiest option
If you have a contactless bank card, phone or smartwatch, you can use ATAC’s Tap&Go system instead of buying a paper BIT every time.
Tap your card or device when you begin the journey. A normal journey is charged at the same €1.50 BIT fare. If you make enough journeys within 24 hours for the €8.50 24-hour ticket to become cheaper, Tap&Go’s “best fare” system automatically applies the better daily price rather than continuing to charge separate BIT fares.
There is one rule tourists frequently miss: use exactly the same payment method throughout the day.
If your first tap is made with your physical Visa card, continue using that physical card. Do not later tap the same Visa card through Apple Pay or Google Pay and assume ATAC sees them as the same thing. The physical card and the digital version on your phone or watch can be treated as different payment credentials, which means your journeys may not be combined for the best-fare calculation.
You should also tap again whenever you change vehicles as required by the Tap&Go system. If the new tap happens while your existing ticket is still valid, it does not mean you are automatically paying another €1.50; it records that you are traveling with a valid fare. ATAC specifically tells passengers to tap when changing transport so that there is no problem if an inspector checks the journey.
Another important detail for families and groups is that one contactless bank card cannot be used to pay for several people traveling together. Tap&Go is individual. Each passenger who needs a paid ticket should use their own valid payment method or have another appropriate ticket.
Children can travel free in Rome
Families should know this before buying transport passes for everyone.
Children up to ten years old travel free on Rome’s ATAC public transport network when accompanied by a fare-paying adult. There is an important exception on Trenitalia railway services inside Rome, where the normal free-travel rule applies only to children under four.
For a family spending several days in Rome, this can change the calculation considerably. Do not automatically buy four transport passes simply because four people are traveling.
Paper tickets must be validated correctly
If you buy a paper ticket, do not simply put it in your pocket and assume that purchasing it made it valid.
The ticket must be validated when you begin the journey. ATAC also requires validation when transferring in the Metro according to the ticket rules. Keep the ticket with you for the entire journey because inspectors can ask to see it.
This is worth taking seriously because the penalty is much higher than the ticket price. ATAC currently states that traveling without a valid ticket, including having a ticket that was not correctly validated, can result in an administrative penalty from €100 to €500 in addition to the ticket price and any applicable procedural costs. The fine is reduced by 50% when paid within five days.
In other words, buying a €1.50 ticket is not enough. Make sure it is valid.
Where Rome transport tickets work
The standard Rome tickets cover much more than only the Metro. Depending on the ticket, they can be used on ATAC buses, trams, trolleybuses, Metro lines and urban sections of participating regional rail services. The Roma 24H ticket, for example, can also be used on bus lines 520 and 720 connecting Rome with Ciampino Airport.
What they do not cover is equally important.
A normal ATAC ticket or Rome transport pass does not cover the Leonardo Express between Termini and Fiumicino Airport, and it does not turn an ordinary Fiumicino airport railway journey into a free ride. Those airport connections have their own fares.
This is another reason not to buy a transport pass expecting it to solve every journey from the moment your flight lands.
Do not depend on a Rome bus when you have a timed ticket
Rome’s buses are useful and inexpensive, but traffic can change journey times very quickly. We use them, but we would never plan an important timed entrance around a bus arriving exactly when an app says it should.
If your Colosseum entrance is at 10:00, do not plan a bus journey that theoretically arrives at 09:55. The same applies to the Vatican Museums, Borghese Gallery and any other attraction where missing the reserved entrance can cost much more than the transport fare you were trying to save.
Give yourself time.
The Metro is usually easier to predict, while buses are better treated as useful transport rather than a guaranteed timetable.
Add this next, preferably after “Do not depend on a Rome bus when you have a timed ticket” and before the fake Tap&Go warning.
Getting Around Rome at Night
Rome does not stop completely when the Metro closes. ATAC runs a separate night-bus network from around midnight until 5:00 in the morning, including routes that replace the main Metro lines after the last trains have finished for the night.
The most useful routes for visitors are the night buses replacing Metro A, B, B1 and C. These are marked nMA, nMB, nMB1 and nMC. For example, nMA follows the Metro A corridor between Anagnina and Battistini, while nMB connects the Metro B corridor between Rebibbia and Laurentina. This means that staying out after the Metro closes does not automatically mean you need to take a taxi.
Rome also strengthened its night service in summer 2026. On Saturday nights, the replacement buses for Metro A, B/B1 and C now run approximately every 8 to 10 minutes throughout the night, with additional staff at several important interchange points including Termini, Colosseo, Piramide, San Giovanni and Tiburtina.
The normal Rome transport tickets and passes can be used on these ATAC night buses, so if you already have a valid 24-, 48- or 72-hour ticket you do not need to buy a special night fare.
We would still check the live route before leaving a restaurant or bar late at night rather than memorizing a timetable in advance. Night services can be changed for road works, events or temporary diversions, and the closest night-bus stop may not be the same stop you used during the day.
For most visitors, the important thing to remember is simply that the Metro closing does not mean public transport has finished. Check the night-bus route first, then decide whether a taxi is actually necessary.
Be careful with fake Tap&Go messages
There is also a new problem visitors should know about in 2026.
ATAC has warned passengers about fraudulent SMS messages claiming that a Tap&Go payment or ticket validation was incomplete and threatening a fine unless the passenger follows a link and makes a payment.
ATAC says it does not send SMS messages concerning Tap&Go validations or payments. If you receive one of these messages, do not click the payment link.
For most visitors, the easiest rule is therefore quite simple: walk when the sights are close together, use the €1.50 BIT for occasional journeys, use Tap&Go if you prefer contactless payment, and only buy an unlimited ticket when your actual itinerary shows that you will use it enough to save money.
