Starting Point and Transportation
The tour kicks off from Koper, where you meet your guide and hop onto a comfortable air-conditioned vehicle. The journey to Postojna Cave takes about an hour, which gives you time to relax and enjoy the Slovene countryside. Reviews mention that the driver is skilled and the bus is comfortable, making the trip itself a nice prelude to the main attractions.
Postojna Cave: The Underground Wonder
Once you arrive at Postojna, you’ll join a guided tour that lasts about two hours. This is the main event, and it truly impresses. The cave system is the largest in Slovenia and the second-largest accessible to the public in the world, with passages stretching over 20 kilometers. Luckily, most visitors only explore a fraction of that—about 5 km—via the electric train and foot.
The train ride inside the cave is a highlight for many. It’s an easy, scenic way to cover a lot of ground while staying warm and comfortable. The cave itself is a labyrinth of stalactites, stalagmites, and other formations, presenting a surreal, almost otherworldly landscape you can’t find anywhere else in the region.
A special feature here is the chance to see the cave’s endangered olms or baby dragons, small white amphibians that are unique to the caves of Slovenia. It’s quite a rare sight and adds an element of conservation interest to the visit. As one reviewer pointed out, seeing these creatures is a highlight that makes the experience more meaningful.
Predjama Castle: The Photo Op and Historical Highlight
After the cave exploration, you’ll enjoy a brief drive (about 15 minutes) to Predjama Castle. This castle is unlike most—it’s built into a towering cliff, seemingly defying gravity. It’s the largest cave castle in the world and makes for an incredible photo stop.
You get around 45 minutes here, enough time to walk around, snap some pictures, and soak in the dramatic setting. The castle’s architecture, perched high above the valley, is striking and offers a perfect contrast to the underground scenery. Several reviews note that this site is a “must-see” and offers a unique glimpse into medieval architecture combined with natural forces.
