The Journey to Postojna Cave

Postojna Cave, often called the “queen of all caves,” is a true marvel. It’s not just a big cavern — it’s a world-renowned karst phenomenon. Over 200 years of visitors have marvelled at its underground tunnels, galleries, and halls. You’ll explore part of the cave on foot, but most of the journey is carried out on an electric train that glides through tunnels and narrow passages. This train ride is a highlight for many, providing a smooth, comfortable way to see the cave’s extensive interior without tiring yourself out.

Inside, you’ll encounter unique features like stalactite formations and the chance to see the proteus (olm) — a rare aquatic salamander that’s a symbol of the cave’s ecosystem. As one reviewer noted, “The cave system is phenomenal,” and the train ride really makes it easy to take in the scale and beauty of this underground world.

The Experience at Predjama Castle

After about three hours exploring the caves, you’ll head to Predjama Castle, perched dramatically on a 123-meter-high cliff. Built centuries ago, this imposing fortress is the only preserved cave castle in Europe. Its history as a defensive stronghold and its unique location make it a fascinating place to walk around.

From the vantage point of the castle, you’ll enjoy stunning vistas over the Lokva River and the lush Slovenian countryside. The castle’s setting is striking, and many reviews mention it as a highlight — “Spectacular sights,” and “a time warp into Slovenia’s medieval past.” The castle’s architecture and history offer a glimpse into how people in the Middle Ages protected themselves using natural elements.

Price vs. Value

At around $137 per person, this tour offers a pretty good deal considering it covers transportation, entrance fees, and a guide. Booking in advance (often around 80 days) shows how popular it is.

What’s Worth Noting?

Some reviews highlight the walking involved — be prepared for paved paths and some uphill sections. The cave environment stays consistently cool (around 10°C), so bringing warm clothing and sturdy footwear is advised.
