What Driving to Greece Actually Costs — and When Flying Wins

ΑThe short version

The cost of driving to Greece is almost entirely fixed per car, not per person. That single fact decides the whole argument: two people often fly cheaper, four people almost never do.

Below is the honest arithmetic for a summer trip from Bucharest to northern Greece, with every figure sourced and the gaps admitted. Prices checked September 2026.

ΒFuel: the one big number

Add the legs and Bucharest to Thessaloniki comes to roughly 750–800 km by the Sofia and Kulata route — Ruse to Kulata alone is about 507 km — so call it 1,600 km there and back. Bucharest to Keramoti, for the Thassos ferry, is about 560 km each way.

Work it with your own car rather than ours. A car using 7 litres per 100 km burns about 112 litres over 1,600 km. In September 2026 petrol cost around €1.60 a litre in Bulgaria and roughly €2.00–2.10 in Greece, so where you fill up matters more than most people think: the same 112 litres is about €180 at Bulgarian prices and closer to €230 at Greek ones.

The practical rule is simple. Fill the tank before the Greek border at Promachonas or Nymfaia, and fill it again in Bulgaria on the way home. Treat Greek fuel as something you buy for local driving, not for crossing countries.

ΓRoad charges: smaller than people fear

For a three-week window covering a two-week holiday:

• Romanian rovinieta, 30 days: €9.50
• Bulgarian e-vignette, one month: €19.90 (two weekly ones cost €20.00, so the month is the better buy)
• Giurgiu–Ruse bridge, leaving Romania: 15 lei, payable online in advance since June 2026
• The same bridge on the way back: reported at around €2
• Vidin–Calafat instead, if you come from the west: €6 each way
• Greek motorway tolls: collected at booths; on the Egnatia Odos it is €0.04 per km plus VAT since January 2026, which makes Thessaloniki to Kavala about €6.95 and the whole Igoumenitsa to Kipoi run €30.45

So the paperwork and the booths come to something in the region of €40–60 for the round trip, depending on route — meaningful, but a tenth of what the fuel costs. The detail sits in the Bulgarian vignette in 2026 and Egnatia Odos tolls.

ΔIf an island is involved

A car ferry is priced per vehicle plus per person, and on the short northern crossings it stays modest. Keramoti to Thassos is €22 for a car up to 4.25 m, €6 an adult and €3 a child — so two adults and two children in a small car pay €40 each way, about €80 return. Longer or wider cars pay €27. Fares and bands for the other northern islands are in taking the car to the northern islands.

ΕThe honest total

For a family of four driving from Bucharest to Kassandra or Paralia Katerini and back, in a car doing around 7 litres per 100 km, filling up mostly in Bulgaria:

• Fuel, there and back: in the region of €180
• Vignettes, bridges and Greek tolls: €40–60
• One optional night on the road: the price of a room, plus the Greek resilience fee if you sleep south of the border

Call it €220–250 for the car, before anything you spend on holiday. Split four ways that is under €65 a person, return. Split two ways it is about €120 each — still cheap, but no longer unanswerable.

What we cannot give you is a flight price. Fares from Bucharest, Cluj and Timisoara to Greek airports move week to week and we will not invent a number; check the airlines directly and compare against the figures above. What we can do is tell you which way the comparison usually falls.

ΣΤDriving versus flying, for two

Two adults going to one place for a week, staying in a resort with a beach in front of it, are the classic case for flying. The drive costs roughly €220–250 of car for two people, plus two days of holiday spent at the wheel. A pair of return tickets often beats that, and always beats it on time.

Flying only wins cleanly, though, if you will not need a car on the other side. Add car hire in July or August — island and mainland rates commonly run from about €50 to €100 or more a day — and a week on wheels costs more than the entire drive did. Fly if your holiday happens within walking distance of the hotel; drive if it does not.

ΖDriving versus flying, for four

With four people the arithmetic stops being close. The car costs the same €220–250 it did for two; four flight tickets, four pieces of hold luggage and a transfer at the other end do not. Add a child seat, a pushchair, a week of groceries bought in Romania and the cool box, and driving is usually several hundred euro cheaper before you have rented anything.

The exception is distance. Driving to Halkidiki, the Olympic Riviera, Thassos or Samothraki is a long day. Driving to Crete or the Cyclades is two long days plus a ferry, and at that point the car has stopped being a saving and become a penance — fly, and read how to book Greek ferries for the hop at the far end.

ΗThe costs people forget

• The Climate Crisis Resilience Fee, charged per room per night at checkout: €2 a night for one and two-star hotels and rented rooms, €5 for three-star, €10 for four-star and €15 for five-star between April and October, much less in winter. A fortnight in a three-star adds €70. Full table in our explanation of the fee.
• Parking. In Paralia, Nikiti or Thessaloniki in August you will pay for it, or circle for it.
• The return fuel is not optional. Budget the whole round trip at the start, not the outbound half.
• A spare day. Ferries are cancelled in strong wind, and a missed boat is a hotel night you did not plan.

ΘSpending less without being miserable

Travel in June or September rather than August: the sea is warm, the roads are empty, the rooms are cheaper and the fee bands are the same. Book accommodation that includes parking. Eat where the food is good rather than where the view is, which is also where it is cheaper — our budget guide to Greece is built around that idea, and our prices page keeps every number on this site with the date it was checked.

The route itself, border by border, is in driving to Greece from Romania; the paperwork is in the border in practice; and if the drive is too long for one push, where to sleep on the way is the companion to this page. Greece from Romania holds the rest.
