Predjama Castle, also known as Predjamski Grad, is a magnificent medieval fortress situated in the picturesque countryside of Slovenia, near the village of Predjama. What sets Predjama Castle apart is its extraordinary location, built into the mouth of a large cave on a towering cliff. The castle's history dates back to the 13th century when a small fortress was constructed on the site. However, the castle, as it stands today, is mainly the result of renovations and expansions carried out in the 16th century. The castle has a rich and intriguing history, filled with legends and tales of knights, sieges, and hidden passages. The architecture of Predjama Castle is a captivating blend of Renaissance and Gothic styles. Exploring Predjama Castle allows visitors to immerse themselves in the medieval atmosphere, walk through its ancient corridors, and imagine the lives of its past inhabitants.

Nice Day in Slovenia I

Caves were unbelievable, and the castle is great. Just wish the castle was a little bit more original and didn’t have so many modern tweaks to make it tourist friendly kinda takes away from the authenticity of the time period. We had a little misunderstanding of the time of the tour in the beginning, but after a couple hours on the phone with Viator, it was figured out, and they rectified the misunderstanding and took us later in the day. The driver and guide was a nice guy, but his speedometer hit 157 km which is high 90s in mile per hour. I understand he knows the roads really well but everyone in the car was a little nervous.

Very beautiful experience. The castle is beautiful and very evocative. The caves are unique; I had already visited other caves previously, but the grandeur of the Postojna caves is something unique

David was an outstanding guide for our Postojna Cave and Predjama Castle tour. He was flexible with our group’s pace, clearly knew the history inside and out, and genuinely went above and beyond to make sure we got the most out of both stops. He made the drive between sites just as enjoyable as the cave and castle themselves, sharing context and stories along the way rather than just shuttling us between stops. If you’re booking this tour, ask for David, he elevated the whole experience

Great way to spend a day; the castle was very interesting; the cave and train ride is spectacular but come prepared with a coat because it is cold in the caves

Cave

This was one of the highlights of my time in Slovenia. Postojna Cave is absolutely breathtaking—photos don't do justice to the scale and beauty of the underground formations. Predjama Castle is equally impressive, with its incredible setting built directly into the face of a cliff. Together they make for an unforgettable day. What really made this tour exceptional, though, was our guide. He was knowledgeable, engaging, and, most importantly, incredibly flexible. He went out of h his way to accommodate the group's interests and pace, making sure everyone had a great experience rather than rushing us from one stop to the next. That personal touch made all the difference. The transportation was comfortable, everything was well organized, and having the entrance fees included made the day completely hassle-free. If you're visiting Slovenia, I highly recommend this tour. It's an outstanding way to experience two of the country's most iconic attractions. Five stars!

Great way to spend a morning. We came from port of Trieste and our guide waited for us, despite being given misinformation by our ship staff. Make sure meeting points are as specific as possible. But David was a great and capable guide. Recommended.

Driver only not tour guide

Driver does not go in cave or castle with you! He was very nice and told us: some stuff along drive. We expected a tour of cave and castle

Wonderful Postjna Cave and Predjama Castle Tour

What a wonderful experience! Dave is a great tour guide. On the way out of Trieste, he told us about the city, the culture and the history/relationship of Italy and Slovenia. He adjusted our route to minimize the drive time to Postojna, hence the name of his company D-tour (LOL). The tour of the Postojna cavern was fantastic. A 10 minute train ride down to the bottom followed by an hour guided tour and a train ride back up. Everything was well organized and tourist friendly. This cavern is a must see. Next stop was the Predjama Castle. Dave helped us setup our phones so we could take the self guided tour without paying for the rental audio devices. A nice lunch onsite and the drive back to our hotel in Trieste. A perfect day. Pickup and drop off were on time as planned. Make sure to dress appropriately for the weather that is cooler than Trieste and the cool cavern temp. Shorts and T-shirt were a little chilly. A suggestion would be to add an audio device or speaker so that the passengers in the back can hear your dialog as we were traveling.

Cave and Castle Visit

Bring layers. Cave is very cold. Lot of strenuous walking uphill inside the cave Castle is very interesting.
