From Trieste: Postojna Cave & Predjama Castle

1. From Trieste: Postojna Cave & Predjama Castle

Postojna Cave, the queen of all caves, is the best-known cave in the world. It is also the greatest tourist attraction in Slovenia and one of the world’s largest karst (limestone) 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.  A fantastic web of tunnels, passages, galleries, and halls, an astonishing diversity of karst features, as well as easy access are certainly the main reasons for the popularity of the cave and the large number of visitors (more than 36 million of them 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 up in the middle of a vertical 123-meter 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 right at the entrance of the cave. During a siege that took place in the 15th century, the castle provided a refuge for its best-known and most notorious owner – Erazem of Predjama.  The legend of 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 that helped the brave knight resist the besiegers without much difficulty for more than a year. Let your guide take you through these unforgettable sights for an ideal day excursion.

Visits of the castle and caves beyond expectations, and the transport from Trieste to Predjama / Postojna really practical with our guide Boris, welcoming and helpful. An opportunity/stop not to be missed for those visiting Trieste even just for a weekend; in addition to the beauty of the visit, the timing required for the tour outside the border (from 9 to 1430) also leaves room for visiting Trieste in the afternoon

Well organized tour that meets customer expectations both in terms of transport and the welcome and guide service. The only flaw to report is the cost of the single trip, double that of the trip as a couple. If a higher price compared to €113 is understandable, a double cost is not appropriate.

Very well organized tour. Transfer from Trieste through the green Slovenian countryside, then the fairytale castle. Finally the caves with the little train that takes you into the heart of the mountain

The trip was great. We enjoyed exploring both sites. The castle has electronic guide so you can progress at your own pace. The cave has a person that leads you through the cave.

Excellent excursion. Comfortable transfer and very attentive guide. It was a spectacular tour.
