The metro is the backbone of getting around in the Athens travel guide. The sections below cover the lines, tickets and passes, how to buy and validate, hours and frequency, the airport link, useful tips and key stations.
What are the Athens metro lines?
The Athens metro has three lines, identified by colour: Line 1 (Green), Line 2 (Red) and Line 3 (Blue). Together they cover 66 stations across the greater Athens area, from Kifissia in the north down to Piraeus on the coast, and from Nikaia in the west to Athens International Airport in the east. The lines interchange at central stations like Syntagma, Omonia and Monastiraki.
The Athens metro is a clean, modern and efficient system that forms the backbone of public transport in the city, and understanding its three lines is the key to using it with confidence. Each line is identified by both a number and a colour. Line 1, the Green line, is the oldest, running north to south from the leafy suburb of Kifissia down through the centre, including Monastiraki and Thissio, to Piraeus on the southern coast. Line 2, the Red line, crosses the city from the western district of Anthoupoli and Nikaia through the centre out to the south-eastern suburbs, calling at key stations such as Syntagma, Akropoli and Omonia. Line 3, the Blue line, runs from the western suburbs through the heart of the city and all the way east to Athens International Airport. Together the three lines link 66 stations across the greater metropolitan area, and they interchange at a handful of central hubs, most importantly Syntagma (lines 2 and 3), Omonia (lines 1 and 2) and Monastiraki (lines 1 and 3), where you can switch lines easily. This compact, well-connected network reaches almost all the major sights. The wider network is set out in the getting around Athens guide. Buying the right ticket is the next step.
How much do Athens metro tickets cost?
A standard single ticket is priced at €1.20 and lasts 90 minutes across the whole network (except the airport), allowing unlimited transfers between metro, bus, trolley and tram. Other options include a €4.10 day pass, a €20 three-day tourist ticket that includes a round trip to the airport, and a separate €9 single airport fare. Tickets work on all public transport.
The Athens metro is excellent value, and choosing the right ticket for your needs keeps costs low. The basic fare is a single integrated ticket costing €1.20, which is valid for 90 minutes from the moment you validate it and, crucially, allows unlimited transfers across the entire urban public transport network, the metro, buses, trolleybuses and the tram, within that time, so a single short hop and a connecting journey both count as one fare; note, however, that this standard ticket does not cover travel to or from the airport. For visitors planning to travel frequently in a day, a 24-hour day pass offers unlimited travel for around €4.10, again excluding the airport. Tourists staying longer benefit from the 3-day tourist ticket, priced at about €20, which gives unlimited travel across the network for three days and conveniently includes one round trip to and from Athens International Airport. The airport itself requires a separate higher fare, around €9 for a single journey, reflecting the longer distance. Reduced fares are available for children, students and seniors. Matching the ticket to your plans, whether a single pass or a multi-day option, ensures you never overpay. The budget angle is covered in the Athens on a budget guide. Knowing how to buy and validate tickets matters just as much.
How do you buy and validate metro tickets?
Buy tickets from automatic machines (with an English option) or staffed windows at every station, paying by cash or card. You must validate your ticket before travelling: tap reloadable Athena Ticket cards or scan paper tickets at the validation gates or yellow machines on entering. Failing to validate risks a fine of around €60, so always validate before reaching the platform.
Using the Athens metro correctly means knowing how to buy and, vitally, how to validate your ticket, as the system relies on validation rather than constant barriers. Tickets are easy to purchase at every station from the automatic vending machines, which offer an English-language interface and accept both cash and cards, or from the staffed ticket windows at the larger stations. The city has largely moved to a reloadable smart-card system, the Athena Ticket, a paper or plastic card onto which you load your chosen fare or pass, though paper tickets are still used. The single most important rule for visitors is that you must validate your ticket at the start of every journey: tap your Athena Ticket card on the reader at the entry gates, or scan or insert a paper ticket, before you proceed to the platform. The 90-minute validity begins from this moment. Skipping validation, even with a valid ticket in your pocket, is treated as fare evasion and can result in an on-the-spot fine of around €60 if inspectors check, so always validate as you enter and keep your ticket until you exit. Following this simple step keeps your journey trouble-free. The process is quick and intuitive once you know it. The metro runs to a reliable timetable.
What are the metro opening hours and frequency?
The Athens metro runs daily from around 5am to midnight, with lines 2 and 3 extending to 2am on Friday and Saturday nights. Trains are frequent, arriving every 5 to 6 minutes at peak times and roughly every 10 minutes off-peak. The airport line (Line 3) runs less often, about every 30 minutes, so check times when heading to the airport.
The Athens metro keeps convenient and reliable hours that suit most visitors’ needs, though it is worth knowing the timetable, especially for late nights and the airport. The system generally operates daily from around 5am until midnight, covering the full sweep of the day for sightseeing, commuting and evening outings. On Friday and Saturday nights, the two newer lines, Line 2 (Red) and Line 3 (Blue), extend their service until about 2am, a useful convenience for those enjoying the city’s nightlife, although the older Line 1 (Green) generally still stops around midnight. Trains are frequent and punctual: during the busy peak hours they arrive every five to six minutes, and even off-peak the wait is usually only around ten minutes, so you rarely linger long on a platform. One important exception concerns the airport: the section of Line 3 serving Athens International Airport runs less frequently than the rest of the network, with trains roughly every thirty minutes, so it is wise to check the schedule and allow extra time when travelling to catch a flight. Outside these hours, night buses and taxis fill the gap. With this in mind, planning journeys is simple. The airport connection deserves a closer look. The airport link is a key route for visitors.
How does the airport metro connection work?
Line 3, the Blue line, runs directly from the airport to central Athens (Syntagma in about 40 minutes) and on to Piraeus, with no change needed. Airport trains run roughly every 30 minutes from about 6.30am to 11.30pm. The airport fare is separate and higher, around €9 single, or included in the €20 three-day tourist ticket, making the metro a cheap, easy airport link.
One of the great conveniences of the Athens metro for visitors is its direct connection to Athens International Airport, which makes arriving and departing simple and affordable. The airport is served by Line 3, the Blue line, whose trains run all the way from the airport station, linked to the terminal by a short walkway, straight into the heart of the city, reaching Syntagma Square in around forty minutes and continuing on to Monastiraki and the port of Piraeus, all without any need to change lines. This single-seat ride is ideal for travellers heading to a central hotel or onward to an island ferry. Airport trains operate at a reduced frequency compared with the rest of the network, roughly every thirty minutes, running from about 6.30am until 11.30pm, so it pays to check the timetable and allow a margin when catching a flight. The fare for the airport journey is charged separately and is higher than the standard ticket, at around €9 for a single trip, but it is included in the excellent-value €20 three-day tourist ticket, which also covers unlimited city travel. For arrivals and departures, the metro is the cheapest and one of the easiest options. The wider airport picture appears in the Athens airport guide. A few final tips smooth your journeys.
What tips help for using the Athens metro?
Top tips: always validate your ticket to avoid a fine; keep it until you exit; beware of pickpockets on busy central trains and at tourist stations; admire the ancient artefacts displayed in stations like Syntagma and Acropoli; use Syntagma, Monastiraki and Omonia to change lines; allow extra time for the less frequent airport trains; and download a metro map or app for easy navigation.
A handful of practical pointers will make using the Athens metro smooth and stress-free. The golden rule, worth repeating, is to always validate your ticket as you enter and keep it with you until you leave, as inspectors do check and the fine for an unvalidated ticket is steep. Stay alert to pickpockets, who can operate on crowded central trains and at busy tourist stations and interchanges, by keeping your bag in front of you and your valuables secure. Take a moment to enjoy a unique feature of the Athens metro: several stations, notably Syntagma, Acropoli and Monastiraki, double as mini-museums, displaying genuine ancient artefacts unearthed during the metro’s construction in elegant in-station exhibitions. For changing lines, remember the key interchange hubs of Syntagma, Monastiraki and Omonia. When travelling to the airport, allow extra time because those trains run only every thirty minutes. Finally, picking up a printed metro map, available free at stations, or using a transport app on your phone makes navigating the network effortless, as the lines and interchanges are simple to follow. With these habits, the metro becomes your easiest way around Athens. It is faster and cheaper than taxis in traffic. The questions below cover the points visitors ask most.
