Tour Details
Postojna Cave and Predjama Castle
After arriving to the port of Trieste, make your way to beautiful Slovenia and prepare for a day of adventure as you travel to Postojna Cave, the best-known cave in the world. Afterwards, the excitement continues as you next visit and experience medieval Predjama Castle, the only preserved cave castle in Europe.
Upon arrival to Postojna Cave, the queen of all caves, you will be amazed as you see for yourself the greatest tourist attraction in Slovenia and one of the world's largest Karst monuments. This is the only place in the world where the underground landscape can be traversed on an electric train and where you get to meet this underground kingdom's most famous inhabitant the proteus (olm) up close.
Experience the fantastic web of tunnels, passages, galleries and halls. Marvel at the astonishing diversity of the karst features and have easy access to all of the main areas of the cave where you will soon understand why this is such a popular tourist destination, more than 36 million visitors in over 200 years.
The Predjama Castle reigns over the surrounding area, not far from the Postojna Cave, in the idyllic village of Predjama. This picturesque, magnificent, defiant, mysterious and impregnable castle has been perched in the middle of a vertical 123-metre high cliff for more than 800 years. Its romantic appeal is further emphasized by the idyllic Lokva River, which disappears into the underground world deep down below the castle.
As the only preserved cave castle in Europe, the Predjama Castle offers a unique insight into the building techniques and resourcefulness of people in the Middle Ages, who were looking for and found a safe harbor for themselves directly at the entrance into the cave. During a siege that took place in the15th century, the castle provided a refuge for its best known and most notorious owner, Erazem of Predjama. The legend about the courageous robber baron Erazem, who remained undefeated until one of his servants betrayed him, is still in people's minds, inspiring and alluring as ever. It was this safe abode of his which helped the brave knight resist the besiegers without much difficulty for more than a year.
