The Role of Buses in Athens
Buses are the backbone of transportation in Athens and across mainland Greece. Within the city, an extensive public network fills the gaps between metro and tram lines, reaching neighborhoods and suburbs throughout Attica. For longer journeys, regional coach companies known as KTEL link the capital with towns and cities across the country, often at very affordable prices.
For visitors, buses offer an economical way to reach popular destinations such as Delphi, Nafplio, Meteora, and Cape Sounion without renting a car. For residents, they provide daily mobility and connections to the main intercity terminals at Kifissos and Liossion.
