How to plan an independent trip to Slovenia

How many days, and in what order?

Three days gets you Ljubljana, Bled and Postojna Cave, and not much else. A week is when the trip starts to make sense. My order would be Ljubljana, then the Julian Alps (Bled, Bohinj and, in summer, the Vršič Pass down into the Soča Valley), then the Karst with Postojna or Škocjan, finishing on the coast at Piran. With ten days I’d add the east, Maribor and Ptuj, which tend to be left out of first trips and which I find the perfect counterpoint. The day-by-day route is in Slovenia in a week.

The best bases

Ljubljana is the obvious base for the first few nights, for the buses and because the centre is walkable. For the Alps, Bled is the most convenient and Bohinj the quietest, both in or right next to Triglav National Park. On the coast I’d pick Piran, which also leaves the Karst within easy reach for a morning. If you head east, Maribor. How to choose each area is in hotels in Slovenia.

Car or coach?

There’s no single answer here. The Tourist Board explains that intercity buses reach almost every village and names Bled, Postojna, Predjama, Velika Planina and Piran as easy coach trips. With that and three bases you can do a complete trip without driving at all.

I want a car for the Alps, though. The Vršič road and the Soča Valley are best enjoyed stopping every few kilometres, and you can’t do that on a bus. Remember that you drive on the right. If you hire, you’ll need DARS’s electronic vignette, €16 for a week or €32 for a month for a car, linked to the number plate and bought at evinjeta.dars.si. From 15 November to 15 March winter equipment is compulsory. I compare the options in getting around Slovenia.

When to go

On the official 2001 to 2010 averages, Ljubljana sits around 22°C in July and just above freezing in January, while up at the Kredarica station on the Triglav massif the annual average is below freezing. The country you find in January has little to do with the one in July. I’d go in June or September if I wanted lakes, mountains and coast on the same trip, and in winter if the plan is skiing. Which months suit which plan, from lakes to skiing, is set out in the best time to visit Slovenia. Sockets are the European two-pin type, so pack an adaptor from home; more in plugs in Slovenia.

How much money to bring

Slovenia has used the euro since 2007 and the Tourist Board talks about an exceptionally high number of cash machines. What weighs most on the budget, more than food, is the entry fees for the headline sights. Bled Castle costs €19 for an adult, Ljubljana Castle €19 with the funicular at the desk, Lipica from €25, and Postojna’s packages run from €34.90 to €84.50. I’d choose carefully, because you don’t need to pay for every Karst cave to understand the landscape. My breakdown is in is Slovenia expensive.

The paperwork, in five minutes

Slovenia sits inside Schengen, so the checks are the ones you’d face in France or Spain. Two passport dates matter to the FCDO, an issue date within the last ten years and an expiry at least three months after you leave the zone, and tourists get 90 days per 180 visa-free. On top of that, the EU’s biometric Entry/Exit System has applied at Slovenia’s airports and ports since April 2026, which can slow the queue on arrival. The Tourist Board also mentions temporary checks at some internal borders, so carry your passport if you pop over to Trieste or Croatia for the day.

Health-wise, a GHIC or EHIC covers treatment that becomes medically necessary in the public system, the FCDO says, but it won’t replace a proper travel policy. I wouldn’t go hiking in the Julian Alps without a policy that covers mountain rescue. If you’re in a private flat rather than a hotel, ask your host about police registration, which has to happen within three days.
