Greece has a surprisingly comprehensive intercity bus network, even if it rarely appears on the radar of visitors who head straight for ferries and planes. The KTEL system — a federation of regional operators rather than a single national company — connects Athens with virtually every corner of the mainland, and with the ferry ports that serve the islands. Once you understand how it is organised, it is one of the cheapest and most practical ways to explore the country.
What KTEL actually is
KTEL (Κ.Τ.Ε.Λ.) stands for "Common Fund of Road Transportation Enterprises," but the name is slightly misleading: it is not one unified company. Each Greek region has its own KTEL cooperative, operating independently with its own routes, timetables, websites and booking systems. The Athens terminal handles most long-distance connections from the capital, while regional KTEL offices act as hubs for their own areas.
The practical effect is that you cannot book a journey from Athens to Thessaloniki through the same website as a journey from Athens to Kalamata. Each KTEL has its own online presence — some polished, some very basic — and booking practices vary accordingly. For some routes, tickets are easy to buy online; for others, turning up at the terminal is still the most reliable approach.
Athens: the two main terminals
Athens has two long-distance KTEL stations, and boarding from the wrong one is a classic mistake:
- KTEL Kifissos (Terminal A) — serves western and northern Greece, the Peloponnese, and the port of Patras. This is the departure point for journeys to Corfu (via Igoumenitsa), Lefkada, Kefalonia and Zakynthos — the ferry ports included in the ticket. Metro passengers can take Line 2 to Agios Antonios, then a taxi or local bus onward.
- KTEL Liosion (Terminal B) — serves central Greece and Evia. Routes to Delphi, Lamia and northern Evia depart from here.
The two terminals are on opposite sides of the city, so always confirm which one your route uses before you set off. The city's main bus information line can help, and most Greek travel blogs keep updated guides.
Athens to Thessaloniki
The flagship long-distance route is Athens to Thessaloniki, a journey of roughly 5–6 hours depending on stops. Several buses run daily, often departing in the morning and evening. Fares are modest compared with the equivalent train, and the coaches are comfortable: air-conditioned, with reclining seats and a luggage hold. The journey runs up the E75 motorway through central Greece, and many passengers find it perfectly comfortable for an overnight departure.
Booking in advance is advisable in summer and around Greek public holidays — the service fills up. The KTEL Thessaloniki website handles tickets for this route.
Getting to the ferry ports
One of KTEL's greatest practical strengths is its coverage of ferry ports. Buses from Athens Kifissos terminal serve:
- Patras — the main port for ferries to Italy (Ancona, Bari, Venice) and for services to the Ionian Islands.
- Igoumenitsa — the northern port for Corfu and Italian ferries.
- Nafplio and Gythio — gateways to the southern Peloponnese and the port of Gytheio for Kythira.
If you are combining a mainland bus journey with an onward ferry, check the KTEL arrival time against your sailing — connections are not guaranteed and KTEL buses can run late in heavy traffic.
Regional routes and island access
On the mainland, KTEL reaches towns that no train can: the deep Mani peninsula, the mountains of Epirus, the villages of the Pelion and Thessaloniki's hinterland in Macedonia. Some routes are seasonal, running more frequently in summer, and frequency drops sharply on Sundays and public holidays across the network.
Several islands have their own local KTEL operations too. Crete, the largest island, has a well-developed KTEL network connecting Heraklion, Chania, Rethymno and Agios Nikolaos. Corfu town is served by local buses from the ferry port. These island networks are separate from the mainland KTEL and are worth researching independently once you have crossed by ferry.
Tickets: buying and checking in
For main routes such as Athens–Thessaloniki, tickets can be bought online or at the terminal kiosk. For smaller regional services, buying at the local KTEL office or boarding with cash is still the norm. A few things to know:
- There are typically fixed seat numbers on longer routes — check your ticket for the seat and coach number before boarding.
- Luggage goes in the hold; the driver or an assistant will load it for you and you collect it on arrival.
- Bring some cash even if you book online — not all terminals or drivers accept cards.
- Timetables vary by season; summer has more frequency on tourist routes, but expect reduced service in January and February.
Tip: For routes to the Ionian Islands (Corfu, Kefalonia, Lefkada), the bus fare from Athens often includes the ferry crossing, making it very good value. Check what your ticket includes when booking.
Comfort and what to expect
Modern KTEL intercity coaches are generally clean and comfortable, with air conditioning that tends to be vigorous — bring a layer even in summer. Longer routes make rest stops of 15–20 minutes at service areas where you can buy coffee and snacks. There is no on-board catering otherwise. Wi-Fi is available on some express services but is not universal.
Journey times are quoted generously in the timetable to account for traffic and stops, so you may arrive earlier than scheduled — useful to know if you have an onward connection. Allow more buffer in Athens itself, where traffic around Kifissos terminal can be slow at peak times.
KTEL and FlixBus
FlixBus has entered certain Greek corridors, including Athens to Thessaloniki and Athens to Patras, and in some cases cooperates with KTEL on joint ticketing. FlixBus tickets can be booked through the FlixBus app, while KTEL services require booking direct. Where both run the same route, compare times and fares — FlixBus sometimes offers a faster non-stop variant, while KTEL may have earlier or later departures that suit your schedule better.

Frequently asked questions
Do I need to book KTEL tickets in advance?
On popular routes — especially Athens to Thessaloniki in summer and around Greek public holidays — booking ahead is strongly recommended. For quieter regional routes, turning up at the terminal often works, but online booking where available avoids queues.
Are KTEL buses comfortable for long journeys?
Yes, on main intercity routes the coaches are modern and air-conditioned, with reclining seats and luggage holds. Longer routes include rest stops. Regional and rural services can be older and less comfortable.
Can I get from Athens to the Greek islands by KTEL?
Directly to the islands, no — ferries are needed. But KTEL serves most mainland ferry ports (Patras, Igoumenitsa) and for some Ionian Islands the bus ticket includes the ferry crossing. See also our guide to getting from Athens airport into the city if you are starting there.
Is there a single KTEL website for all of Greece?
There is a central KTEL portal that covers some routes, but because each regional KTEL operates independently, you may need to check individual regional websites for tickets on less-served corridors. A journey-comparison site is useful for finding which KTEL operates a given route.
