Practical Guide to Public Transportation in Greece

Published on October 1, 2025 and written by Cyril Jarnias

Greece, the cradle of Western civilization, offers much more than its paradise beaches and ancient ruins. For expatriates choosing to settle there, understanding the public transportation system is essential for successful integration. Whether you’re in Athens, Thessaloniki, or on one of the many islands, here’s everything you need to know about public transportation in Greece.

A Diverse Network for All Your Travel Needs

Greece has a varied and continuously improving public transportation network, particularly in major cities. In Athens, the dynamic capital, you’ll find a modern and efficient public transport system, the result of massive investments made for the 2004 Olympic Games.

The Athens Metro, the true backbone of the network, includes three lines serving the city’s main neighborhoods. Clean, punctual, and air-conditioned, it’s the preferred mode of transport for Athenians and tourists alike. Line 3, nicknamed the “blue line,” even connects downtown to the international airport in just 40 minutes.

Buses and trolleybuses effectively complement the underground network. Although sometimes crowded during peak hours, they offer extensive coverage of the city and its suburbs. The tram, meanwhile, is particularly appreciated for connecting downtown to the southern beaches of Athens, providing a pleasant and scenic alternative to other modes of transport.

In other major cities like Thessaloniki, the bus network is the main public transportation method. Although less developed than in Athens, it remains effective for getting around the city.

For inter-island travel or trips to the mainland, ferries are essential. The port of Piraeus, near Athens, is the country’s main maritime hub, offering regular connections to most Greek islands. These crossings, while sometimes lengthy, provide a unique experience and spectacular views of the Aegean Sea.

Transportation Budget: How Much to Plan for Your Daily Commute?

For expatriates in Greece, public transportation costs are generally considered reasonable, especially compared to other European countries. However, it’s important to budget this expense correctly for optimal financial management during your expatriation.

In Athens, the single ticket valid for 90 minutes on all transport modes (metro, bus, tram) costs €1.20. For regular users, a monthly pass is available for approximately €30, offering unlimited access to the entire network. These rates are significantly lower than those in capitals like Paris or London, making Athenian public transport particularly attractive for expatriates.

For those planning to frequently use public transport, including trips to the airport, the 3-day tourist pass at €20 can be interesting. It includes a round trip to the airport and unlimited network access for 72 hours.

In other Greek cities, rates are generally similar, or even slightly lower. In Thessaloniki, for example, a bus ticket costs about €1, while a monthly pass is around €30.

For inter-island travel, the budget can vary considerably depending on distance and ferry type. An Athens-Santorini trip on a fast ferry can cost between €50 and €80, while a conventional ferry will be cheaper but take longer.

As an expatriate, it’s wise to plan a monthly budget of approximately €50 to €100 for public transportation, depending on your place of residence and travel habits. This amount can increase if you plan frequent trips between islands or to the mainland.

It’s important to note that reduced fares are available for certain categories, including students, seniors, and children. If you fall into one of these categories, don’t hesitate to inquire about discounts you might be eligible for.

Tips for Optimizing Your Travel in Greece

Living in Greece as an expatriate requires some adaptation, particularly regarding transportation. Here are some tips to make the most of the Greek public transport system:

1. Master Mobile Apps: Major transport companies offer apps allowing you to plan your trips, purchase tickets, and track bus or metro schedules in real time. The OASA Telematics app for Athens is particularly useful.

2. Opt for Transport Cards: If you reside in Athens or a major city, investing in a rechargeable transport card (ATH.ENA Card) will save you time and money. These cards can be loaded with different types of tickets or subscriptions.

3. Take Advantage of the Tap2Ride System: This new contactless payment system, available in Athens, allows you to pay directly with your bank card or smartphone, greatly simplifying your occasional travel.

4. Plan Your Inter-Island Travel in Advance: Ferries can fill up quickly during high season. Booking in advance will not only guarantee you a spot but often at a more advantageous rate.

5. Explore Alternative Transport Options: In some cities or islands, bike-sharing or electric scooters can be an interesting option for short trips.

• Familiarize yourself with schedules: Greek public transport, although generally reliable, may have reduced schedules on weekends or during holidays.
• Learn a few Greek words: Although many signs are in English, knowing some basic Greek words can greatly facilitate your travel.
• Be vigilant about pickpockets: As in any major city, remain attentive to your personal belongings, especially in crowded transport.

Challenges and Opportunities of the Greek Transport System

Although the public transport system in Greece has seen significant improvements in recent years, it still presents some challenges that expatriates should be aware of:

Punctuality: Although the situation has clearly improved, particularly in the Athens Metro, delays can still be frequent in buses or ferries, especially during peak tourist season. It’s advisable to allow some extra time in your travel plans, particularly for important appointments.

Network Coverage: While major cities like Athens and Thessaloniki benefit from a well-developed transport network, rural areas and some islands may have more limited coverage. In these regions, owning a personal vehicle may prove necessary.

Overcrowding: During peak hours, public transport, particularly buses and the metro in Athens, can be very crowded. This can be a challenge for expatriates accustomed to more personal space.

However, these challenges also come with opportunities:

Continuous Improvement: The Greek government constantly invests in improving transport infrastructure. For example, the extension of Athens Metro Line 3 towards Piraeus port, recently completed, has significantly improved the city’s connectivity.

Adoption of New Technologies: The introduction of the Tap2Ride system in Athens is an example of the willingness to modernize the transport network. These innovations make public transport use increasingly convenient and accessible.

Sustainable Development: Greece is increasingly committed to sustainable transport policies. The introduction of electric buses in Athens and the development of bike lanes in several cities demonstrate this orientation toward more ecological transport modes.

For expatriates, these developments represent an opportunity to contribute to a more sustainable lifestyle while benefiting from a continuously improving transport system.

Conclusion: Navigating the Greek Transport System as an Expatriate

The public transport system in Greece, although presenting some challenges, offers an effective and economical solution for expatriates’ daily commutes. Whether you’re based in Athens, Thessaloniki, or on one of the many Greek islands, understanding and using public transportation will not only reduce your expenses but also allow you to fully immerse yourself in the local culture.

The key to making the most of the Greek transport system lies in planning and adaptation. Familiarize yourself with the different options available in your region, invest in monthly passes if you’re a frequent user, and don’t hesitate to combine different transport modes to optimize your travel.

Remember that the public transport system in Greece is constantly evolving. Stay informed about new lines, fare changes, and technological innovations that could improve your travel experience.

Finally, consider public transportation not only as a means of getting around but also as an opportunity to discover Greece from a different angle. Bus or ferry rides can offer spectacular views and enriching encounters, adding an extra dimension to your expatriate experience in Greece.
