One of the best things i did in Slovenia was a day trip to Postojna Caves & Predjama Castle. 🐉🏰 I took the bus, which took a little over an hour, and spent most of the day here. You will need to buy tickets in advance for the caves as you can only go in with a tour at a specific time. Predjama Castle doesnt have tour times, but can be purchased in a combined ticket. It has a self guided tour. You...

Reviews Summary

Visitors consistently praise Postojna Cave for its breathtaking natural beauty and the unique experience of exploring its vast chambers via an underground train. The informative tours and the chance to see the rare proteus are frequently highlighted as memorable aspects. However, some find the entrance process chaotic and the modern additions to the cave, like the train carts, detract slightly from the natural ambiance.

"This is the coolest thing I did in Slovenia by far. We had an incredible tour guide and the train is super fun. The formations inside are truly incredible and you get to see a good portion of the cave without it being too strenuous. Would definitely recommend bringing a jacket though as it is constantly 10° in there."

Sophie Clarke

"I found it a great experience. It's cold ❄️ so dress accordingly. The cave was spectacular and I learned a lot about the cave with the audio guide.

The proteus 🐊 was another highlight for me.

I find a couple things could be improved, hence -1 🌟. The carts and the locomotive 🚂 look cheap and basic. There's a lot you could do to make it look more appealing.

Obviously people come for the spectacular cave, but it would be nice having an actual locomotive in the front and rock-like looking wagons. The ticket prices would easily finance this improvement over time.

Also the entrance to the cave was very stressful and chaotic. I would have liked an automated machine telling you where to go. Or only letting you in like the Vintgar Gorge if it were your turn. Seemed amateurish for a big tourist attraction.

However the cave remains well worth visiting."

Joseph Dumuter

"One of the most incredible experiences to have in Slovenia. The train ride through the cave is phenomenal. The whole history of the place and its natural beauty are truly wonderful.
I recommend arriving early at the entrance, which is still about 200 meters from the parking lot. The train departs exactly on time"

In-depth insights and expert knowledge

The Geological Marvel of Postojna Cave

Postojna Cave is a karst cave system, meaning it was formed by the dissolution of soluble rocks like limestone. Over millions of years, water has carved out an intricate network of passages, chambers, and galleries, creating the stunning formations visitors see today. The cave is home to a diverse array of speleothems, including stalactites (hanging from the ceiling) and stalagmites (rising from the floor), which grow at an incredibly slow rate, often just a few centimeters per century. The sheer scale of the cave, with its vast halls and intricate passages, is a testament to the immense power of natural erosion. Reddit

One of the most striking features is the Concert Hall, a massive chamber capable of holding thousands of people, renowned for its natural acoustics. The cave's unique ecosystem also supports a variety of life, most famously the proteus (or olm), a blind amphibian that has adapted to life in complete darkness. The Vivarium at Postojna Cave allows visitors to observe these fascinating creatures up close, offering a glimpse into a world rarely seen. Reddit

The cave's accessibility is a key part of its appeal. A narrow-gauge electric railway transports visitors deep into the cave system, making it accessible to a wide range of visitors, including those with mobility challenges. This unique mode of transport adds an element of adventure to the exploration, allowing visitors to cover significant distances without strenuous effort. Reddit

Navigating Your Visit: Tips from Fellow Travelers

Many visitors emphasize the importance of dressing warmly, as the cave's consistent 10°C (50°F) temperature can be quite a shock, especially if you're visiting during warmer months. Packing a jacket or sweater is a recurring piece of advice across various travel forums and social media. Comfortable walking shoes are also essential, as you'll be traversing uneven terrain for a significant portion of the tour. Reddit+1

To ensure a smooth experience, booking tickets online in advance is highly recommended. This helps bypass potentially long queues at the entrance and guarantees your spot, especially during peak tourist seasons. Travelers also advise arriving at the cave entrance a bit before your scheduled tour time, as the train departs promptly, and you wouldn't want to miss it. Reddit

Finally, remember to pay for parking at the designated kiosk before attempting to exit the premises. This small but crucial step can prevent unexpected delays and ensure a hassle-free departure. Following these practical tips from those who have already visited can significantly enhance your overall enjoyment of Postojna Cave. Reddit
