Exploring Slovenia often means uncovering its hidden gems, and a half-day excursion to Idrija offers a fascinating glimpse into the country’s unique past. This tour, rated a perfect 5.0 by travelers, takes you from Ljubljana to the historic town of Idrija, renowned for its mercury mine, its impressive Gewerkenegg Castle, and its delicate Idrija lace. The experience combines history, craftsmanship, and scenic beauty in a compact, well-rounded package.
What I particularly like about this excursion is how smoothly it’s organized—your driver takes care of logistics, leaving you free to focus on the sights and stories. I also appreciate the depth of the mine tour, guided by knowledgeable locals like Milan, who make the history come alive with engaging narration. On top of that, the castle visit is a treat, featuring a collection of Idrija lace that underscores the town’s artisanal flair.
A possible point to consider is that the mine tour isn’t suitable for travelers with claustrophobia. Descending into Anthony’s Shaft can be intense for some, but if you’re comfortable with confined spaces, it’s a highlight. This trip offers excellent value—combining transportation, guided insights, and entry fees, it makes for a hassle-free way to explore a UNESCO site without the expense or time of a full-day trip.

Exploring the UNESCO Heritage of Idrija

The journey begins with a comfortable pickup from Ljubljana—your driver and guide, Milan, or someone like him, will whisk you away for a roughly 90-minute ride into the heart of Slovenia’s mercury mining history. This early history is quite the story: legend says mercury was first spotted in Idrija back in 1492, the same year Columbus set sail, which adds a fun historical tie-in. The town’s mercury mine was once the second-largest in the world, only surpassed by the mine in Almadén, Spain.
The mine tour itself is a genuine highlight. Descending Anthony’s Shaft, you get a real sense of what life was like for the miners—something that’s hard to grasp from reading alone. Travelers like Thea S commented on how informative and insightful the guide was, adding that “the visit of the mercury mine was highly interesting.” The tour is carefully timed, with about an hour and a half allocated, so you get plenty of detail without feeling rushed.
Entrance is included, which makes this a cost-effective way to experience a UNESCO site. Just keep in mind if you’re claustrophobic or uncomfortable in tight spaces, this part of the trip may not be for you. That said, the setting is well-preserved and offers a tangible connection to the past that’s both educational and eye-opening.

Medieval Charm and Artisanal Heritage at Gewerkenegg Castle
After emerging from the depths of the mine, you’ll head over to Gewerkenegg Castle, built between 1522-1533. Its name—meaning “mine castle”—reflects its original purpose to protect the mining operation. Today, it’s a museum showcasing 500 years of mining history, but the true treasure is the collection of Idrija lace.
The lace-making craft has been part of Idrija for over three centuries. Walking through the castle’s exhibits, you’ll see intricate cloths, napkins, earrings, necklaces, and even gloves—all made with delicate bobbin lace. One reviewer noted the castle courtyard is beautifully decorated, adding to the picturesque charm of the town. It’s a chance to appreciate a craft that has helped shape Idrija’s identity for generations.
The castle visit lasts roughly 45 minutes and is included in the tour price. It provides a peaceful moment after the intense underground experience and offers plenty of opportunities to photograph the historic architecture and artisanal displays.
