Athens operates a combined metro, tram, suburban rail, and bus network under a unified fare structure administered by OASA (Athens Urban Transport Organization). The metro system consists of three numbered lines designated M1 (green), M2 (red), and M3 (blue), covering approximately 85 kilometers with 61 stations as of 2024. Line 1 runs from Piraeus port through central Athens to Kifisia in the northern suburbs, operating partially above ground on its original 1869 steam railway alignment. Line 2 connects Anthoupoli in the northwest to Elliniko in the south, passing through Syntagma and Omonia squares. Line 3 runs from Nikaia through the city center to Athens International Airport in Spata, a 39-kilometer route completed in stages between 2000 and 2013. All three lines intersect at Syntagma Square, the primary transfer station located directly beneath the parliamentary building.
The metro operates from approximately 5:30 AM to 12:30 AM on weekdays, with extended service until 2:00 AM on Fridays and Saturdays. Trains arrive at intervals of 3 to 10 minutes during peak hours and 7 to 15 minutes during off-peak periods, with longer waits on Line 1's northern and southern termini. A single journey ticket costs €1.20 and remains valid for 90 minutes across all OASA services including transfers, while a 24-hour ticket costs €4.10 and a five-day tourist ticket costs €8.20 as of 2024. Tickets require validation at blue or yellow electronic readers before entering platforms, with fines of €60 imposed for unticketed travel. Line 3 to the airport requires a separate €9.00 ticket for the full journey from central Athens, though standard tickets work for intermediate stations before Koropi.
The Athens tram network operates three routes along a 27-kilometer coastal corridor from Syntagma Square to the southern suburbs. Route T3 runs from Syntagma to the Peace and Friendship Stadium in Neo Faliro, Route T4 continues from SEF to Voula, and Route T5 connects Syntagma directly to Voula via Glyfada. Trams depart every 5 to 12 minutes during daytime hours and every 30 to 40 minutes after midnight, with 24-hour service on Fridays and Saturdays. The coastal route passes Faliro beach, Glyfada marina, and terminates near organized beaches in Voula, making it the primary public transport access to Athens's swimming areas. Standard OASA tickets apply without surcharge.
The suburban railway (Proastiakos) connects Athens with Corinth to the west, Chalkida to the north, and the airport to the east, operating on Greek Railways infrastructure with OASA fare integration within Attica. The airport line shares tracks with Metro Line 3 from Doukissis Plakentias station but continues as suburban rail service with larger vehicles and luggage storage. Journey time from Syntagma to the airport via Metro Line 3 measures 40 minutes, while the suburban rail from Larissa Station takes 35 minutes with fewer intermediate stops. Trains to Corinth and Chalkida serve outer Attica suburbs not reached by metro lines, departing every 15 to 60 minutes depending on route and time.
Bus routes in Athens number over 300, divided into standard urban routes, express airport routes (X93, X95, X96, X97), and 24-hour services. The X95 bus operates continuously between Syntagma Square and Athens International Airport with departures every 15 to 30 minutes, completing the journey in 50 to 90 minutes depending on traffic. Route X96 connects the airport to Piraeus port for cruise ship passengers, running 24 hours with similar frequency. Night bus routes (prefixed with N) replace metro service between 12:30 AM and 5:30 AM, operating at 20 to 60 minute intervals on major corridors. All buses display route numbers and destinations in Greek and Latin alphabets on front and side panels, with digital screens showing upcoming stops inside vehicles.
Trolleybuses operate on 22 electric routes throughout central Athens, distinguished by overhead cables and three-digit route numbers (001-022). These vehicles climb hills more effectively than diesel buses and serve neighborhoods with steep grades including Lycabettus Hill and Strefi Hill areas. Trolleybus route 11 from Kypseli to Piraeus passes through dense commercial districts on Patission Street and connects major transport hubs at Omonia and Karaiskaki squares. The trolleybus network uses the same €1.20 ticket as all OASA services.
Taxis in Athens display mandatory roof lights showing "TAXI" in Greek and English, with lights illuminated when available for hire. Meters start at €1.29 daytime flag fall (5:00 AM to midnight) or €1.60 nighttime rate, adding €0.74 per kilometer within city limits and €1.29 per kilometer outside the municipal boundary marked at Dafni monastery to the south and Agia Paraskevi to the northeast. Minimum fare stands at €3.47 regardless of distance. Additional charges include €1.07 per piece of luggage over 10 kilograms, €3.84 for trips to or from the airport, €1.07 from port or bus stations, and €1.07 for radio dispatch booking. Drivers must provide printed receipts showing start and end times, distance, and fare breakdown upon request. The Beat and Free Now mobile applications allow advance booking with English-language interfaces and credit card payment, though street hails remain common and vehicles legally cannot refuse destinations within the Athens basin.
Ride-hailing applications Uber and Bolt operate in Athens offering only licensed taxi connections rather than private vehicles, functioning as dispatch services with fare estimates matching metered rates. Private ride services remain prohibited under Greek transport regulations enacted in 2018, which restrict smartphone-based passenger transport to vehicles holding professional taxi licenses issued by municipal authorities.
Car-sharing services include Avance, EasyMove, and Mobility, offering hourly or daily vehicle rental through smartphone applications with designated pickup zones in central neighborhoods including Kolonaki, Exarchia, and Pangrati. Rates start at approximately €0.19 per minute or €45 per day including insurance and fuel, with vehicles returned to any authorized parking space within the service area. Electric scooter sharing through Lime, Bird, and Wind places thousands of devices throughout pedestrian areas, charged at €0.25 to unlock and €0.15 per minute of use. Athens municipality designates permitted parking zones and prohibits scooter use on archaeological site perimeters, with geofencing automatically reducing speeds near the Acropolis and Ancient Agora.
Bicycle infrastructure in Athens expanded significantly after 2020 with the installation of 180 kilometers of marked lanes, though separated cycle paths remain limited to coastal routes and specific corridors like Panepistimiou Street. The municipal bike-sharing system operates approximately 150 stations across central districts, charging €0.50 for 30 minutes with daily and weekly subscription options. Bikes must be returned to physical docking stations unlike scooters, with availability displayed in the eBike Athens mobile application. Cyclists face challenging conditions on many arterial roads where painted lanes disappear at intersections and marble-paved historic streets create slippery surfaces during rain.
Walking remains the practical choice for distances under two kilometers in central Athens, where archaeological sites cluster within the Plaka, Monastiraki, and Thissio neighborhoods. The Grand Promenade (Dionysiou Areopagitou Street) forms a continuous pedestrian corridor from the Temple of Olympian Zeus past the Acropolis south slope to the Ancient Agora, covering 2.5 kilometers on marble and concrete pavement shaded by bitter orange trees. This route connects most UNESCO World Heritage sites within the historical center without crossing vehicle traffic. Pedestrian traffic lights display numeric countdowns showing seconds remaining before signal changes, though enforcement of red signals varies significantly by district and time of day.
Ferry connections to islands depart from three Athenian port areas administered separately. Piraeus, located 10 kilometers southwest of Syntagma, operates as the primary hub for Aegean islands with nine numbered gates (E1-E9) serving different island groups. Saronic Gulf islands including Aegina, Poros, and Hydra depart from gates E8 and E9, Cyclades destinations from gates E6 and E7, and Crete from E2. Metro Line 1 terminates at Piraeus station 800 meters from the gates, requiring a walk or local bus connection. Rafina port, 30 kilometers east of Athens on the Attica coast, serves Cyclades islands including Andros, Tinos, and Mykonos with less congestion than Piraeus and direct bus connection via KTEL route from Agiou Konstantinou terminal in central Athens. Lavrio port, 60 kilometers southeast near the archaeological site of Sounion, operates limited ferry service to Kea, Kythnos, and some Cyclades islands, accessible via KTEL bus from Mavrommateon terminal.
The Athens International Airport "Eleftherios Venizelos" sits 33 kilometers east of central Athens in Spata municipality, handling 28 million passengers in 2023 according to airport authority statistics. Ground transport options include Metro Line 3 (40 minutes to Syntagma, €9.00), suburban railway (35 minutes to Larissa Station, €9.00), express bus X95 to Syntagma (50-90 minutes, €5.50), express bus X96 to Piraeus (60-90 minutes, €5.50), express bus X93 to Kifissos bus terminal (50 minutes, €5.50), and express bus X97 to Elliniko metro station (45 minutes, €5.50). All airport express buses operate 24 hours with air conditioning and luggage racks. Taxis to central Athens cost €38.00 flat rate during daytime and €54.00 during nighttime hours according to 2024 regulated pricing, with trip duration varying from 35 to 90 minutes based on traffic conditions on Attiki Odos ring road.
Long-distance buses to destinations throughout Greece depart from two main terminals. Kifissos Terminal A, located 4 kilometers northwest of Syntagma, serves northern and western Greece including Thessaloniki, Ioannina, Patras, and the Peloponnese through KTEL regional cooperatives. Terminal B at Liosion Street, 3 kilometers north of the center, operates routes to central Greece including Delphi, Meteora, and Volos. Each KTEL cooperative operates as an independent entity with separate ticketing, pricing, and schedules, meaning no unified booking system exists. Tickets require purchase from terminal offices or specific agencies rather than from drivers, with prices regulated by distance at approximately €0.06 per kilometer. Metro Line 2 stops at Agios Antonios station 600 meters from Kifissos Terminal A, requiring a walk or short taxi connection.
Railway services from Athens operate from Larissa Station, located 2 kilometers north of Syntagma and connected by Metro Line 2. Trains to Thessaloniki depart five to six times daily with journey times of four hours on standard service or 3 hours 45 minutes on Intercity expresses, covering 520 kilometers at fares ranging from €24 to €50 depending on service class. The Proastiakos suburban network uses the same station for regional services to Corinth, Kiato, Chalkida, and the airport. Greek Railways (OSE) operates limited domestic routes compared to pre-2010 levels, with international connections to North Macedonia and Bulgaria suspended since 2020 according to current timetables. Tickets require advance purchase from station windows or automated machines, with no onboard sales.
Congestion in Athens concentrates during morning hours from 7:30 to 9:30 AM and evening hours from 5:00 to 8:00 PM, particularly on ring roads Attiki Odos and Kifisias Avenue, and radial routes including Vouliagmenis Avenue to the coast and Mesogeion Avenue toward the airport. The Daktylios (ring) system restricts private vehicle access to the central 3.5-square-kilometer area on alternating days based on license plate numbers, with odd-numbered plates allowed on odd dates and even-numbered plates on even dates, though enforcement decreased after 2019. Parking in central districts costs €2.00 to €4.00 per hour at metered spaces marked with blue paint, operating from 9:00 AM to 9:00 PM on weekdays and 9:00 AM to 4:00 PM on Saturdays. Residents display special permits for free parking in their registered zones. Yellow curbs indicate absolute no-parking areas with immediate towing to municipal impound lots, requiring payment of €100 removal fee plus €8 daily storage.
Traffic enforcement cameras operate at major intersections throughout Athens, automatically issuing fines for red light violations (€700), bus lane usage (€200), and restricted zone entry during Daktylios hours (€80). Speed cameras on Vouliagmenis Avenue and Kifisias Avenue photograph vehicles exceeding posted limits of 50 to 70 kilometers per hour, with fines starting at €40 for minor infractions and scaling to €350 for speeds exceeding limits by 30 kilometers per hour or more. Payment within 10 days reduces fines by 50 percent, while unpaid violations prevent vehicle registration renewal.
