The Itinerary in Detail

Pickup and Transportation

The tour starts with a pickup from your designated meeting point in Ljubljana, specifically at City Hotel Ljubljana (Dalmatinova ulica 15). The small group approach means you won’t be part of a large bus full of strangers, which makes the experience more relaxed. Your chauffeur-guide, with their local knowledge and friendly demeanor, will take care of the driving, so you can sit back and enjoy the scenery en route.

The ride to Postojna takes approximately an hour, during which your guide shares tidbits about Slovenia and points out sights along the way. It’s a nice way to get oriented, especially if you’re new to the area.

Postojna Cave: A Natural Wonder

Once at Postojna Cave, you’ll immediately appreciate why it’s considered one of Slovenia’s top attractions. This cavern has been carved out over two million years by the Pivka River, leaving behind a stunning network of tunnels, stalactites, stalagmites, and columns that have formed into incredible shapes.

The most iconic part of the visit is the underground train ride, which lasts about 10 minutes. The train whisks you into the heart of the cavern, giving you a sense of the vastness and complexity of this underground world. After disembarking, you’ll explore on foot, walking through illuminated halls and narrow passages.

One review highlights the experience: “The cave is an amazing wonder of nature. I thought this is just similar to the cave in Halong Bay of Vietnam but this is bigger and indeed the mother of all caves!” (Kathrina_D). The tour includes access to notable sections like the Hall of Tubes, where thin, transparent stalactites hang from the ceiling, and the Concert Hall, which features impressive formations.

What to Expect Inside the Cave

Prepared for a constant temperature of around 10-12°C, you should dress warmly, even if it’s warm outside. The floors inside are paved and safe for walking, but sturdy shoes are essential. As one reviewer noted, “Appropriate footwear required; no flip flops!” This ensures you can walk comfortably and safely through the sometimes damp environment.

The guided commentary enhances this part of the trip, sharing stories about the cave’s formation, its early visitors, and some interesting facts. Some guests mentioned the pace can be brisk — “the guide walks very fast,” so if you prefer a more leisurely walk, keep that in mind.

Predjama Castle: A Fortress Built into the Cliffs

After exploring the caverns, you’ll hop back into the vehicle for a short drive to Predjama Castle. This 13th-century fortress is unlike any other, built into a high cliff with a gaping mouth that looks more like a movie set than a castle. Perched 123 meters above the valley, it has long captured travelers’ imaginations.

On arrival, you’ll enjoy the sweeping views from the terrace of a cozy country inn before touring the castle itself. The castle features holes in the ceiling designed to pour boiling oil on invaders, dark dungeons, and secret hiding spots like Erazem’s Nook. A guide will share stories and legends, bringing the history alive.

Inside the Castle

The castle’s interior isn’t filled with treasures or antique furniture but fascinates with its architecture and location. One reviewer described it as “interesting” because of its strategic placement and the way it was integrated into the natural landscape. It’s a good place to imagine medieval life and some of the castle’s colorful legends.

Return to Ljubljana

After about an hour exploring the castle, your guide will take you back to Ljubljana, arriving at your original meeting point. The timetable is flexible and well-structured, ensuring you get the most out of the half-day adventure without feeling rushed.
