Travel Arrangements


At the crossroads between Europe and the Middle East, Athens has never been more accessible. The award-winning Athens International Airport services 130 countries and is the gateway to dozens of Greek islands and mainland destinations.

For more information please visit the Athens International Airport.


The Athens public transport system is affordable, reliable and covers most of the city and suburbs. You can use all means of public transport using the same ticket (a single ticket costs €1.20 and is valid for 90 minutes). 


The fastest means of getting around Athens is the Metro. The Athens Metro system consists of 3 lines and connects to the tram, bus routes and suburban railway. 

The Metro runs daily from 5 am to midnight. Lines 2 and 3 operate until 2 am on Fridays and Saturdays. At peak hours, trains run every 5-6 minutes.

Buses & Trolleybuses

The Athens bus and trolleybus network is very extensive. Most buses and trolleybuses run daily from 5 am to midnight, but do check the timetable of your route. 

Airport Express buses operate on a 24-hour basis. These services connect Athens International Airport with the city centre (Syntagma Square), Piraeus port and the Intercity Bus Terminal (KTEL Kifissos).
