Which Are the Caves Open for Touristic Tours in Slovenia?

There are more than 10,000 caves in Slovenia, and we still discover about 100 new each year. Unfortunately, these beautiful underground worlds are not always open for touristic tours. If you come to Slovenia, visiting the caves is a must-do, and you will not be disappointed.

To have the best experience possible, the most important is to know which caves are open for touristic tours. There are five very touristic caves: Postojna Cave, Škocjan Cave, Kostanjevica Cave, Vilenica Cave, and Križna Jama Cave.

You will also find smaller and less touristic caves if you are not a big fan of crowds. Let’s take a look at the caves, and the timetables and prices for touristic tours.

Postojna Cave

Postojna Cave is the most visited and most touristic Cave in Slovenia. In this Cave, you will find the actual baby dragons talked about in the local legends and a 140 years old railway.

Postojna cave is the only one where you will find such a railway. It will take you entirely underground to discover one of the largest stalagmites, called the Skyscraper. It is about 16-metre-high.

Around 38 million visitors from the whole world visited Postojna Cave, going down the 5-kilometer railway.

The particularity of Postojna Cave is the fact that olms live there, and you can observe them. They are the creatures we often call baby dragons. These translucid pink vertebrates with extraterrestrials looks can live up to 100 years old and more than eight years without any food.

The caves in Slovenia foster more than 150 animal species, and the olm, or Proteus anguinus, is the largest one.

Postojna cave is made for you if you are an animal lover since it is the karst with the most biodiversity. In one of its corridors, you will even find a vivarium. For the first time in the last 200 years, we have been able to watch olms hatch.

The Less Touristic Caves in Slovenia Giving Tours

If you are not into crowds, but you still want to visit caves and karsts in Slovenia, do not worry. There is an important number of less touristic caves that still give great tours and that are worth seeing.

The Divača Cave can be visited since the 19th century and is an unusual cave that will satisfy your wishes for adventure and wonder. It is close to the Škocjan Caves and is crossed by the same Reka River.

This Cave was visited by many famous people such as Sigmund Freud or the Austro-Hungarian crown prince Rudolph whom the Cave was named after for a while.

You can visit the Divača Cave from May 1st to September 30th every Sunday at 11am, and in July and August, every Tuesday, Thursday, and Saturday at 10am.

The Dimnice Cave is close to Slivje and Markovščina. An unusual phenomenon happens all the time in the Cave creating a column of smoke. This is why it is called Dimnice Cave (dim means smoke in Slovene).

You can visit Dimnice Cave every Sunday at 3.30pm.

Experience Slovenia Caves!

Visiting Slovenian Caves is a great experience to discover marvelous landscapes and subterraneous treasures. Although not all 10,000 caves are open to visitors, you can still take a tour of many of them. The most touristic caves are famous for their magnificent underground scenery but do not forget smaller caves around Slovenia where you might discover unique karsts.
