A Day Exploring Slovenia’s Hidden Gems: Postojna Cave & Predjama Castle Small Group Tour
When you think about Slovenia, chances are your mind jumps to picturesque lakes and charming old towns. But for a truly memorable experience, a visit to the Postojna Cave and Predjama Castle offers a fascinating glimpse into the country’s natural wonders and medieval history. For around $79 per person, a 5-hour small group tour from Ljubljana takes you to these two highlights, accompanied by knowledgeable guides who add local stories and insider tips to make it more than just sightseeing.
What makes this tour stand out? First, you’ll get to explore Postojna Cave, the country’s most famous subterranean wonder, complete with a train ride through underground galleries that seem to go on forever. Second, the castle perched on a cliff at Predjama is a sight straight out of a fairy tale, with a storied past and seasonal charm. We especially appreciate the expert guides — like Branko, who reportedly shares stories with humor and enthusiasm, making history come alive. Plus, the small group size ensures a more relaxed, personalized experience, avoiding the crowded feel of larger tours.
One point to consider is the cost of admission fees—around €45.50 for both attractions—which is separate from the tour price. Also, since the cave is cool and damp year-round (about 9°C / 48°F), packing warm clothes and comfortable shoes is essential. This tour is ideal for those who enjoy a mix of natural beauty and medieval architecture, and don’t mind a bit of walking or uneven terrain. It’s perfect for travelers wanting a well-organized, insightful overview of Slovenia’s top sights without the hassle of arranging transport or guides themselves.

The Postojna Cave: Slovenia’s Underground Marvel
We loved the way the tour begins with a comfortable air-conditioned minivan ride from Ljubljana, setting a relaxed tone for the day. The journey itself is scenic, giving you a glimpse of Slovenia’s lush countryside. Once at Postojna, the experience truly begins with a special train ride through a labyrinth of tunnels and caverns. This train, a highlight in itself, whisks you through the dark, cool passages of the world’s most visited cave system.
Inside, you’ll marvel at the stalactites and stalagmites of all shapes and sizes, some resembling bizarre sculptures or natural chandeliers. The guide will point out underground lakes and caverns, with a focus on how these formations have evolved over thousands of years. One unique feature is the chance to see the Proteus anguinus, a rare, blind aquatic creature known as the human fish, which has adapted to life in total darkness. This highlights the ecological importance of the cave and adds an element of wonder for nature lovers.
The temperature of 9°C (48°F) inside means you should bring warm clothing—once you’re inside, you’ll appreciate being prepared. The tour lasts about 3 hours, giving plenty of time to appreciate the underground scenery without feeling rushed.
Predjama Castle: A Medieval Wonder on a Cliff
After the cave, the journey continues with a scenic drive to the spectacular Predjama Castle. Perched dramatically on a cliff face, the castle looks almost as if it’s part of the landscape, built into the rock itself. This medieval fortress is perched high on a vertical cliff, and the structure’s striking appearance is something you won’t forget.
Our guides, like the enthusiastic Monica and Branko, share stories about the castle’s most famous resident, Erazem of Predjama, a legendary robber knight. The castle’s chambers, staircases, and secret passages invite curiosity, and exploring them offers a real sense of history and adventure. The surrounding scenery varies with the seasons—from blossoms in spring and summer to fiery autumn leaves, or snow-covered vistas in winter, each providing a different backdrop for photos.
The 1-hour stop at Predjama is perfect for wandering at your own pace, soaking in the views, or snapping photos of this fairy-tale structure. The castle’s position on a cliff, combined with its history, makes it a favorite for those who love stories of medieval intrigue.
The Itinerary: What You’ll Experience
The tour kicks off from Dalmatinova ulica 10, the meeting point in Ljubljana, and includes a scenic drive to Postojna Cave. After about an hour on the road, you’ll arrive for a guided tour of the cave, including the train ride, stalactite formations, and underground wildlife. Returning to the van, you’ll spend about an hour traveling to Predjama Castle, where you’ll explore its chambers and take in the views. The tour wraps up with a scenic drive back to Ljubljana, arriving at your starting point on Dalmatinova ulica.
