Do you need a car in Slovenia?

Almost every guide to Slovenia says the same thing: rent a car, the country is small, the roads are good. Two of those three are true, and the conclusion still does not follow for a lot of trips.

Slovenia is genuinely small, about the size of Wales, and you can cross it in four hours. That cuts both ways. It means a car is convenient, and it also means the distances are short enough that not having one costs you very little.

What a hire car actually costs here

The daily rate is the part people compare, and it is the smallest part of the bill.

• A vignette for Slovenian motorways, which hire cars sometimes have and sometimes do not. A weekly one is about 16 EUR and driving without it is a fine that starts at 300.
• Parking in Ljubljana, roughly 1 to 2 EUR an hour in the centre, and the old town is closed to cars entirely.
• Parking at Bled, 3 to 4 EUR an hour in summer, and the lakeside spaces fill by mid-morning.
• Fuel, around 1.65 EUR a litre.
• The cross-border fee if you picked the car up in Croatia or Italy, which is often larger than the rental itself.

A week of that, on top of a 40 EUR a day rental, lands somewhere near 450 to 550 EUR before you have driven anywhere interesting.

The four questions that actually decide it

Forget the general advice. The answer turns on four specifics, and you can settle it in a minute.

• Are you staying in Ljubljana? If yes, the car is a liability for the days you are in the city. The centre is pedestrianised, parking is a garage on the edge, and everything inside the ring is walkable.
• How many separate day trips do you want? One or two, and individual transfers are cheaper. Four or more, and a car starts to win.
• Is anyone in the group willing to drive on the third day of a holiday? The Vršič pass has fifty hairpins and the Karst roads are narrow. Some people find that the point of the trip and some find it the end of it.
• Are you going to drink wine? The Vipava and Brda valleys are wine regions, and Slovenia's limit is 0.5, effectively zero for the driver.

What Slovenia without a car actually looks like

Better than the guides suggest, because the country is compact and the sights are clustered.

• Ljubljana needs no transport at all. It is a walking city and the old town is closed to traffic.
• Bled is 55 km and a transfer is €70 for a saloon, per car. The town is walkable once you are there and the lake path takes ninety minutes.
• The Postojna Cave is 53 km, €70, and Predjama Castle is ten minutes further on the same trip.
• Piran is 120 km, €135, and cars cannot enter the old town anyway. Everyone parks outside and takes the shuttle in, so a car buys you nothing at the far end.
• The train to Bled, Postojna and the coast exists and is cheap, but the stations are outside the towns and the timetable is thin outside commuting hours.

The arithmetic, done properly

A five-day trip with three day trips out of Ljubljana. Bled, Postojna with Predjama, and Piran.

• Hire car: about 200 EUR for five days, plus vignette, fuel and parking, so 320 to 380 EUR all in. Plus two days of it sitting in a garage while you are in Ljubljana.
• Three return transfers: roughly 550 EUR at the return-trip rate, and you never park, navigate or drive.
• Two of the three as a day with a driver, at €350 for the saloon and €440 for the five-seat van, and the third as a straight transfer: about the same as the transfers, with several stops instead of one.

So the car is cheaper on paper for this shape of trip, by roughly 200 EUR. Whether 200 EUR is worth two days of parking, one mountain road and the wine you did not drink is not an arithmetic question, and anyone who tells you it is has not driven into Bled in August.

When a car is clearly right

• You are staying outside a town, in the Soča valley, the Karst or a farm stay.
• You are here for more than a week and moving base more than once.
• You want to drive the Vršič pass or the Panoramic road, which are the point rather than the transport.
• You are four people doing something different every day, where the per-trip cost of transfers adds up quickly.

When it is clearly wrong

• A city break in Ljubljana with one or two excursions.
• A first trip where nobody wants to drive a foreign motorway from the airport at eleven at night.
• A wine trip, for the obvious reason.
• A winter trip, when the alpine passes close and winter tyres are a legal requirement from mid-November.

The useful version of the advice is not rent or do not rent. It is: decide where you are sleeping first, count the days you would actually use the car, and price the days you would not. For a lot of Slovenia trips the honest answer is a car for two days and nothing for the rest, which nobody sells and everybody can arrange.
