English The destination is a cave, not a city
Postojna's main attraction lies underground: kilometres of galleries, chambers and rock formations, some of which are visited aboard a small electric train, one of only a few of its kind in the world. That means your transfer is not about reaching a town centre, but the entrance to the cave complex, where the guided visit begins.
The cave is also home to the olm, known as the "human fish", a blind amphibian that lives in underground waters and has become a symbol of the area. It is a very different experience from Slovenia's coast or lakes, and that shapes how you plan your arrival.
The visit is timed: arrange your pick-up around your tour
Postojna Cave is visited on guided tours at set times, and during the peak season it is worth booking your time slot in advance. As the journey from the airport is short, the pick-up time can be planned around your tour, allowing enough time after your flight rather than the other way round.
Ten degrees all year round, even in August
The cave stays at a constant temperature of around 10 °C throughout the year. Bring a jacket or jumper in your luggage, even in the height of summer. It is easy to have one ready when your transfer drops you directly at the entrance.
How to get from Ljubljana Airport to Postojna
Ljubljana Airport to Postojna is around 70 km and takes less than an hour, entirely within Slovenia with no border crossing. The route joins the A1 motorway south-west towards the coast before reaching the entrance to the cave complex. It is one of the shorter transfers in the area, making it ideal for a half-day trip.
Predjama Castle, built into the rock, and the route to the coast
Just a few kilometres from the cave stands Predjama Castle, built into the mouth of a cave beneath a cliff. It is one of Europe's most unusual castles and a popular addition to a visit to Postojna Cave. And because Postojna lies on the A1 motorway towards the Adriatic, many transfers use it as a stop on the way to Piran, Portorož or Trieste.
This dual role — the end of a day trip or a stop en route — is worth mentioning when you book, as it changes the journey time and route.
Vehicle, groups and half-day trips
As it is a short journey, it is common to book a return transfer for the same day, or combine it with Predjama Castle and the coast. In these cases, it is worth arranging the pick-up time for the return as well as the arrival, and choosing a vehicle suitable for the size of your group.
You can view the options in the Zonetransfers fleet. For visits including a stop at Predjama or continuing towards the coast, the chauffeur service in Ljubljana allows you to travel with the driver at your disposal. Stops and waiting times are subject to the service terms.
