Postojna Cave, Slovenia, the most beautiful and best-known cave in the world!

When we write about travelling we tend to talk more about the big countries, but this doesn’t mean the smaller ones aren’t beautiful, or even more beautiful than the super known ones.

One example is Slovenia – a small country with beautiful landscapes and amazing places. If you want to go somewhere fantastic this holiday, Slovenia is the place to be.

Therefore, if you decide to trust us and listen to our recommendation, please book a visit to Postojna Cave, a spectacular and interesting place to visit, that will leave you breathless.

I’ve visited this wonderful cave a few years ago and I was really impressed by its structure – I felt like I was entering a complete and new world.


The cave was first described in the 17th century by Johann Weichard Valvasor and a new area of the cave was discovered accidentally in 1818 by local Luka Čeč, when he was preparing the hitherto known parts of the cave for a visit by Francis I, the first Emperor of Austria.

According to, electric lighting was added in 1884 preceding even Ljubljana, the capital of Carniola and in 1872 rails were laid in the cave along with first cave train for tourists.

After 1945, the gas locomotive was replaced by an electric one. 5.3 km of the caves are open to the public, the longest publicly accessible depth of any cave system in the world.

The greatest tourist attraction in Slovenia

Postojna Cave, formed by the Pivka River, is a 20 km (12.5 mi) long karst cave, reached 34 million tourists in 200 years and is the most visited cave in Europe.

Prepare to be impressed by the fantastic web of tunnels, passages, galleries and halls. Moreover, caves also feature an incredible concert hall, famous for its unique acoustical values. The hall can seat up to 10,000 people, and is frequented by symphony orchestras and soloists.

The great tour

Your journey begins with a 2 km (1.2 mi) ride into the caves, which is a thrilling experience in and of itself.  You will see stunning stalactites, stalagmites, calcite, and other incredible geological formations, as well as a wealth of wildlife.

You will enjoy the second part on foot and admire playful stalactite forms in no hurry – the tour lasts approximately 90 minutes.

The most beautiful stalactite in the Postojna cave is called the Brilliant – an approximately 5-metre-tall stalagmite, according to

The ‘Brilliant’ stands in a spot with a strong and even drip from the ceiling. A thin layer of pure calcite sinter is deposited constantly and evenly by the water trickling down the rounded crown of the stalagmite.

That is why it looks so extremely white and shiny, and it is not surprising that it has been the symbol of Postojna Cave and the Slovenian Karst for decades. A pillar stands next to it in true baroque splendour.

The Dragon of the Cave

Postoja Cave is home to the human fish or olm, a salamander-like animal that lives only in these specific caves. In simple words, this means that an adult keeps most of its juvenile features.

This means all human fish are babies that have taken on adult functions. And if we imagine that the human fish should decide to grow up… Wouldn’t it perhaps really grow into a dragon?

We hope we succeeded to gain your interest and this gorgeous place and in conclusion, we leave you with the words of Dr. E. H. Costa: “Everything is created as if it was made by the most gracious, most educated artist; and yet this miracle was created by the blind nature in complete darkness”.
