Exploring the Highlights of the Tour

A Comfortable and Guided Introduction to Slovenia’s Natural Wonders

This trip begins with your guide picking you up from your hotel or cruise terminal in Trieste, which takes away the stress of navigating on your own. The transportation is included in the price, and the journey itself offers a scenic drive through Slovenia’s countryside. The small-group limit of 15 ensures you’re not lost in a crowd, and the experience feels more like traveling with friends than a large tour bus.

Postojna Cave: Nature’s Masterpiece

Postojna Cave is often called the “queen of caves,” and once you see it, you’ll understand why. It’s the most famous cave in Slovenia and among the largest karst monuments in the world. The electric train ride inside the cave is a standout feature — a fun way to explore the vast underground network of tunnels, galleries, and halls, all accessible with ease. The web of passages stretches over a long distance, and you get an up-close look at stalactites, stalagmites, and other karst formations.

One of the most fascinating inhabitants of the cave is the proteus (olm), sometimes called the “human fish,” which you can meet up close during your visit. The diversity of the cave’s features — from shimmering formations to underground chambers — makes it a visual feast. Travelers comment on how breathtaking and large the caves are, with one reviewer saying, “The caves are magnificent. We had never seen anything like them in our travels.”

The tour includes about three hours at Postojna, giving you plenty of time to marvel at the formations, enjoy the train ride, and absorb the informative commentary provided by your guide. It’s an accessible experience, even for those who might worry about walking long distances, thanks to the train and relatively straightforward paths inside.

Predjama Castle: Medieval Drama on a Cliff

Just a short drive from the caves, Predjama Castle offers a striking contrast: a castle built into the side of a towering 123-meter-high cliff. The castle’s dramatic setting has made it a symbol of resilience and ingenuity since the 13th century. It’s the only preserved cave castle in Europe, and exploring it provides insights into medieval building techniques and life.

The castle’s romantic and somewhat mysterious aura is enhanced by its location above the underground river Lokva, which disappears into the depths below. The story of Erazem of Predjama, the infamous robber baron who used the castle as a refuge during a siege, adds a layer of intrigue. The legend of a knight resisting besiegers for over a year still captures visitors’ imaginations.

Your guide will narrate these legends and explain how the castle’s strategic position helped its inhabitants defend themselves, making it more than just a pretty face. The one-hour visit allows time to explore the rooms, courtyards, and passageways, many of which have uneven stairs—so good footwear is advisable. Reviewers praise the interpretive stories and the stunning views, with one noting, “The castle was very interesting and the drive in Slovenia is beautiful.”
