- Postojna Cave - 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 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, astonishing diversity of karst features, as well as easy access are certainly the main reasons for such popularity of the cave and a large number of visitors (more than 36 million of them in over 200 years).
- Predjama Castle - 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 into 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 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.

Only thing is that it was very cold so take a big jacket and long pants. It gets pretty cold in the caves. Ernest was a very nice tour guide.

Fantastic tour! Ernest... - Fantastic tour! Ernest was a fantastic host! We were on a cruise and booked on Viator. Our family booked through cruise ship. We spent a lot of time at castle and our family got a drive by at the castle for more money. Loved everything about this tour!

Wonderful experience - The size of the caves just took our breath away. From the moment we entered them on the train we were enthralled. The castle was interesting but had a lot to live up after the caves. The driver from Koper trips was excellent and very informative and I would certainly use them again.

Avoid this trip - A terrible experience. Collected in a bus with no air conditioning, it was ridiculously hot ! We then had to pick up other guests 45 minutes away !
After coming out of the caves ( which are fabulous) , the bus driver was an hour and fifteen minutes late as he’s left to pick up school children from the local school !
The journey back took hours as again we had to detour to drop off other cruise passengers . The result was a 5 hour tour actually took 8 hours !!
I would 100% NOT RECOMMEND this trip .
Ernest the young guide was wonderful and did his best with what was a group of very unhappy customers

Avoid this tour operator - Great guide, amazing caves and castle, but a lousy tour operator, which took away from the experience. A 5 hour tour turned into 8 due to a series of lazy decisions and poor planning by the tour operator. Unscheduled bus pick- ups and stops, bus delays (driver didnt return after lunch), and 3-4 hours in a hot (un air conditioned) bus led to a sweaty and cranky set of passengers. Apparently, not the first time, so avoid this operator and go with someone else.
