Do you need a car in Santorini?
Yes — with caveats. On an island like Santorini a car (or ATV) genuinely earns its keep, because the KTEL buses are limited and get packed at peak season, mostly radiating from Fira. But an International Driving Permit is legally required, the caldera-edge roads are narrow and winding, and there is essentially no parking in Oia or Fira itself. Rent for the days you actually plan to explore the island, not the whole stay.
- Rent a car for Santorini if you want to reach the beaches, wineries, and quieter villages — the KTEL bus network is limited and hubs mainly through Fira.
- An International Driving Permit is a legal requirement for non-European visitors, including Americans and Israelis — rental desks and police both enforce it.
- Parking in Oia and Fira is nearly nonexistent — both villages are pedestrian-first, so you park at the edge and walk in.
- The caldera-edge roads are narrow and winding — many tourists rent ATVs instead, but a proper car is the safer choice if you're not experienced on two wheels.
KTEL buses are limited and hub through Fira
Santorini's public bus network (KTEL) connects most villages, but nearly every route passes through the central station in Fira, which makes cross-island trips slow and indirect. Buses get very crowded in peak season (June–September), and schedules thin out in the evening and shoulder months. A car or ATV gives you direct, on-demand access instead of routing everything through one hub.
An International Driving Permit is a legal requirement, not a suggestion
Greece legally requires non-European visitors — including Americans, Israelis, and other non-EU/EEA licence holders — to carry an International Driving Permit alongside their home licence. Rental companies check for it at the counter, and police checkpoints on the island enforce it too. Without an IDP, you risk being refused the car outright, and any insurance coverage becomes void if you're stopped without one.
Narrow, winding caldera roads — and a lot of ATVs
The roads along the caldera rim between Fira, Imerovigli, and Oia are narrow, cliff-hugging, and busy with tour buses, scooters, and pedestrians. Many visitors rent ATVs or scooters instead of cars for the novelty and easier parking, but accidents involving rented ATVs are common on the island. If you're not confident on two wheels, a standard car is the safer choice, driven carefully.
Parking in Oia and Fira is nearly nonexistent
Both Oia and Fira are pedestrian-first villages with almost no parking near their centers. The practical approach is to park in a designated lot at the edge of the village and walk in — trying to drive into the center, especially in Oia at sunset, usually means gridlock. Plan extra time to park and walk, particularly if you're chasing the sunset crowds.
Airport and ferry arrivals can be chaotic
Santorini's airport (JTR) is small and can back up quickly during peak-season arrivals. The ferry port at Athinios, where most ferries dock, is known for chaotic, poorly organized arrivals with taxis, buses, and rental shuttles all converging at once. Confirm your rental pickup point and process in advance — whether it's airport, port, or hotel delivery — so you're not navigating that scrum unprepared.
