Piran: Postojna Cave and Predjama Castle

2. Piran: Postojna Cave and Predjama Castle

Your tour will begin with Postojna Cave, one of the best-known caves in the world. It is also 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 can meet this underground kingdom’s most famous inhabitant, the proteus (olm), up close. A fantastic web of tunnels, passages, galleries and halls, astonishing diversity of karst features as well as easy access are certainly the main reasons for the popularity of the cave and a large number of visitors. From here the tour extends to the Predjama Castle which 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-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 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 which helped the brave knight resist the besiegers without much difficulty for more than a year.

From Ljubljana: Skočjan Caves Half-Day Trip

3. From Ljubljana: Skočjan Caves Half-Day Trip

The Škocjan Caves are a unique natural phenomenon, created by the Reka River. The Reka River springs below the Snežnik plateau and flows for 55 kilometers (34 miles) on the surface. After reaching the karst — that is, the limestone surface — the river not only deepens its riverbed through erosion but also corrosion; it dissolves the limestone and creates the caves. Explore the Škocjan Caves with a local, English-speaking guide on this half-day trip from Ljubljana. Get picked up at your hotel or guesthouse at 8:30 AM, then drive to the caves as your guide informs you about Slovenia. Upon arrival at around 9:30 AM, your guide will help you to buy the tickets to enter the cave. At 10 AM, begin your tour of the caves, spending around 1 hour and 45 minutes inside. Marvel at how big the caves are and learn all about the things you see. Make sure to dress warmly as the constant temperature in the caves is between 8–10ºC (46–50ºF). After your tour, you can eat something at the restaurant near the ticket counter if you wish. Finally, get back in your vehicle at 12 PM and return to Ljubljana. The tour concludes with drop-off at your original pickup point at approximately 1 PM.

Several days after the Postojna Cave we also visited the Skocjan Caves. The two caves are so different that they are definitely worth visiting. Postojna is tailored entirely to tourism, the stalactites are bizarre and spectacularly beautiful. Skocjan, on the other hand, is the elemental force of nature, not pimped up, but completely original. Unfortunately it is not allowed to take pictures there; on the other hand, it is also an option to look at things with your eyes and not with the camera. The visit to the Lipica Stud had the small drawback that there were no horse demonstrations that day. Anyone who attaches particular importance to this should find out about the days on which such demonstrations are offered before booking the tour with the organizer or the stud. The visit was worth it anyway, because there was a detailed German-speaking tour and you had the opportunity to come into direct contact with the horses in the stables.

We LOVED the Skocjan Caves. We've visited a number of caves around the US and this one was spectacular in comparison. This tour does require some fitness as there are a lot of stairs and a lot of up & down throughout the tour. It was unfortunate that they don't allow any photography during the tour but you can see why, it would really slow down the tour. The area around the caves was very beautiful and luckily we were able to see the beginning of the fall colors. The Lipica Stud Farm was interesting but it would've been nice to see some kind of performance while we were there.

We have loved this tour to all the participants that met that same day. I think it is the best tour that Roundabout Travel offers for the itinerary and content. The tour guide was the best I've had in Slovenia: Tusi Polonca. He was very close, cheerful and managed to keep the group very excited and united. Thank you very much Tusi!

Leon was fantastic, he was informative and fun. He obviously loves his country and was enthusiastic to share that with us. The castle and caves are a must see and if you're lucky enough to have Leon as your guide you are sure to enjoy your day.

It was interesting and a bit disappointing at the caves as we not allowed to take pictures,but rules are rules. The tour guide was fantastic
