Athens has a modern metro system that is unusual in any city: it passes directly alongside, and in some cases beneath, significant ancient ruins, with several stations doubling as small museums displaying artefacts unearthed during construction. Three lines connect the city's main districts, and an integrated network of buses, trolleybuses and tram extends coverage to the coast. For a capital that was late to build its metro, Athens now has one of the most historically atmospheric underground systems in the world.
The three metro lines
Athens Metro (operated by STASY, formerly ISAP and ATTIKO METRO) has three lines, each colour-coded:
- Line 1 (Green) — ISAP: the oldest, dating to 1869 in its original form. It runs from Kifissia in the leafy northern suburbs to Piraeus, the main port, through the city centre at Omonia and Monastiraki. Much of this line is elevated or at street level rather than underground. It is slower and older than Lines 2 and 3, but connects key destinations including Piraeus for ferries to the Greek islands.
- Line 2 (Red): the first modern metro line, opened in 2000. Runs northwest from Anthoúpoli through the centre (Syntagma, Akropoli, Syngrou-Fix) and southeast toward Elliniko. The Akropoli station is a highlight — its glass cases display ancient finds from the excavation, and you emerge just metres from the Acropolis Hill.
- Line 3 (Blue): runs from the airport (Doukissis Plakentias junction) all the way to Haidari in the west, with an extension to Nikaia under development. The main segment passes through Syntagma (the central interchange), Monastiraki and the archaeological sites area before heading toward the harbour at Piraeus via an interchange. The Airport Express operates on this line using special trains running non-stop or with limited stops between the airport and city centre.
The key interchange hub is Syntagma, where Lines 2 and 3 cross directly beneath Syntagma Square — the political heart of Athens, next to the Greek Parliament and the National Garden. Monastiraki connects Lines 1 and 3, and is the most convenient stop for the Plaka and Acropolis area.
Stations as archaeological museums
During construction of Lines 2 and 3 in the 1990s, archaeologists uncovered thousands of artefacts spanning thousands of years of continuous Athenian history — pottery, coins, skeletal remains, ancient water pipes. Rather than simply cataloguing and storing them, the metro authority built illuminated display cases directly into the station walls and concourses. The effect is striking:
- Syntagma station — probably the most impressive, with a cross-section of ancient Athenian soil visible through glass and dozens of finds displayed. Allow a few minutes to look properly.
- Akropoli station — artefacts from the excavation beside the Acropolis Hill.
- Monastiraki station — finds from the ancient Agora area.
- Evangelismos station — displays from the excavation on a busy central avenue.
These are not replica displays — they are real excavated objects in their metro context, free to view for any passenger with a valid ticket.
Trams
Athens has a modern tram network running from the city centre south through the coastal suburbs to the seaside district of Glyfada and the Peace and Friendship Stadium. The tram is the main public transport link to the Athens Riviera — the strip of beaches, seafront restaurants and resort towns along the Saronic Gulf. It runs along the seafront promenade for much of its route, making for a pleasant journey in fine weather. Tram tickets are separate from the metro (though integrated passes cover both) and operate on a tap-on system.
Buses and trolleybuses
OASA (the urban transport organisation) runs the surface bus and electric trolleybus networks covering parts of the city not reached by metro or tram. Trolleybuses run on overhead electric wires and are common in the central area. Buses extend to outer suburbs and serve destinations like the port at Piraeus where the Line 1 metro is inconvenient. The network is extensive but timetables can be harder to predict for visitors; the OASA Telematics app shows real-time arrivals.
Tickets and passes
Athens uses an integrated ticketing system covering metro, bus, trolleybus and tram (the airport connection requires a special fare):
- Single journey ticket: valid for 90 minutes on all modes (metro, bus, tram) with free transfers within the time window. The tram has its own validator on board.
- 24-hour pass: unlimited travel on all modes (excluding airport) for 24 hours from first validation. Practical for a full sightseeing day.
- 5-day tourist pass: five days of unlimited travel on all city modes, typically combined with the airport express at a combined fare. Good value for a week-long stay.
- Airport ticket: a separate, higher-fare ticket is required for travel between the airport and the city on Line 3. The standard city ticket does not cover the airport section. Return airport tickets are available at a slight discount.
Tickets are available at all metro stations (machines have English menus), at the airport metro counter, and at some convenience stores and newsstands. Validate at yellow validators on entering the metro gate, on tram platforms, and on-board buses. Plain-clothes and uniformed inspectors operate regularly.
Getting to and from the airport
Athens Eleftherios Venizelos International Airport (ATH) is connected to the city by Line 3 of the metro — but this requires a special airport ticket, not covered by standard urban passes. The journey from the airport to Syntagma takes around 40–45 minutes on the express service. Trains run every 30 minutes through the day and less frequently at night. The airport express is fast and reliable, avoiding the often heavy Attica highway traffic.
Airport buses (Express Bus lines X95 to Syntagma and others to Piraeus) are cheaper and run 24 hours, but significantly slower in traffic — the journey can be an hour or more during busy periods.
Getting around the main sights
For first-time visitors, the metro is the efficient way to link the main archaeological zone:
- Acropolis and Acropolis Museum: Akropoli station on Line 2, then a 5–10 minute walk uphill.
- Ancient Agora and Thissio: Thissio station on Line 1, or Monastiraki (Lines 1 and 3).
- National Archaeological Museum: Victoria or Omonia on Line 2, then a 10-minute walk.
- Syntagma Square and changing of the guard: Syntagma on Lines 2 and 3.
- Monastiraki flea market and Plaka: Monastiraki on Lines 1 and 3.
The Acropolis, Ancient Agora and surrounding archaeological zone are best explored on foot once you have arrived at the right metro station — the area is compact and the connections between sites are part of the experience.
Tips for getting around Athens
- Athens in summer can be extremely hot. The metro is air-conditioned; surface transport and walking in midday heat are less comfortable. Plan sightseeing for early morning or late afternoon.
- Validate your ticket before every journey — inspectors operate on all modes and fines are issued to tourists and residents alike.
- The metro typically runs from around 5.30 am to midnight on weekdays, and later (to around 2 am) on Friday and Saturday nights.
- For island hopping from Athens, the port at Piraeus serves most Cyclades and Dodecanese routes; Rafina port (northeast of the city, served by bus) is closer for some Cyclades ferries.
- Consider the Schengen 90/180-day rule if combining Greece with other European countries on a longer trip from outside the EU.
Frequently asked questions
Does a regular Athens metro ticket cover the airport?
No. Travel between the city and Athens Airport on Line 3 requires a special airport ticket, which costs more than a standard city single. Standard daily or 90-minute city tickets do not cover the airport segment. A combined airport–city pass is available and may be worth buying on arrival.
Which metro station is closest to the Acropolis?
Akropoli station on Line 2 (Red) is the closest — named directly for its proximity. From the station exit it is a 5–10 minute uphill walk to the main Acropolis entrance. Monastiraki on Lines 1 and 3 is a longer walk but brings you through the charming Plaka neighbourhood.
How do I get to Piraeus to catch a ferry to the Greek islands?
Take Line 1 (Green) to its southern terminus at Piraeus station. The journey from Monastiraki or Omonia takes around 15–20 minutes. The ferry departure piers at Piraeus are spread over a large area — check your ferry's specific gate number in advance and allow extra time to walk to the right dock.
Is the Athens tram useful for visiting beaches?
Yes. The tram runs south from the city centre along the coast through Paleo Faliro and Glyfada — the most accessible beaches and seaside areas from central Athens. It is slow but scenic. The nearest beaches to the city are a 30–40 minute tram ride from the terminus near Syntagma.
