A Closer Look at the Tour Experience

This tour combines two of Slovenia’s most remarkable attractions in a logical and engaging way. Starting from Koper, you’ll depart in a modern van equipped with air conditioning—perfect for the Slovenian summer or cooler months. The journey itself offers scenic views that set the tone for the day, with the driver and guide sharing interesting tidbits about the region, as one reviewer noted, “the panorama during the drive is also wonderful,” making the transit part of the adventure.

Inside Postojna Cave

Once you arrive at the entrance of Postojna Cave, you’ll be greeted with anticipation for what’s ahead. Your guide, who speaks excellent English, will give you a rundown before hopping on the electric train that whisks visitors through the labyrinth of tunnels. This train ride is a highlight for many—it’s a fun, effortless way to see the cavern’s most captivating formations, including towering stalactites and strange rock sculptures.

One reviewer, Szonja, shared how this “unusual underground train experience” exceeded her expectations, mentioning that she received more than she initially anticipated. The cave’s internal temperature stays around 10°C (50°F), so packing a jacket is wise, especially if you’re prone to feeling chilly.

Exploring the Cave on Foot

After the train ride, you’ll spend approximately 1.5 hours walking through designated pathways, with plenty of opportunities for photos. The guides focus on making the experience engaging, pointing out interesting features and sharing stories about the olm, often called the “baby dragon,” which is unique to this environment.

Photography inside the cave is permitted but flash is discouraged to protect the delicate formations. The dim, mysterious lighting makes for atmospheric photos, so bring your camera with a good zoom lens or wide-angle to capture the stalactites and stalagmites in all their glory.

Break and Free Time

Following the guided tour, there’s a short break—around 30 minutes—giving you time to browse the gift shop, buy souvenirs, or grab a quick snack. This flexibility is appreciated, especially after walking through the cool depths of the cave.
