Greece is best explored by car once you leave Athens. Islands like Crete and Rhodes, the Peloponnese, Meteora and the Pelion peninsula all reward independent travellers.
The right choice is usually a small, robust car. Village roads are narrow, beach access tracks can be rough, and rental contracts often exclude unpaved roads and ferry crossings.
Which car to rent in Greece, by situation
Summer
Heat, air conditioning, coast roads and crowded car parks.
Hot summers, narrow village roads and tight parking near beaches make a small car with good air conditioning the easiest choice. Fuel use is also low on island loops.
Winter
Cold starts, rain, ice, snow rules and winter equipment.
Lowland Greece is mild in winter, so a compact is sufficient. Mountain areas such as Arachova, Metsovo or Pelion can see snow, so ask about chains for those trips.
Mountain roads
Passes, hairpins, gradients, gravel and weather that changes fast.
Mountain roads in the Peloponnese, Crete and northern Greece can be steep and rough. A compact SUV offers clearance and confidence without being too wide.
Long road trips
Hundreds of kilometres, tolls, fatigue, luggage and fuel stops.
The main routes between Athens, Thessaloniki and the Peloponnese are tolled motorways in good condition, and a compact car is comfortable enough for those distances.
