Postojna Cave – One of the World’s Most Famous Caves

Next, it’s off to Postojna Cave, often called the “queen of all caves” and the most visited in Slovenia. This underground wonderland is a karst marvel, spanning vast tunnels, galleries, and halls. What makes it unique is the electric train ride that transports visitors deep into the cave system—something that makes exploring easy and accessible, even for those with mobility considerations.

Within the cave, you’ll encounter stalactites, stalagmites, and other formations that have taken hundreds of thousands of years to develop. One of the cave’s most famous residents is the proteus (olm), which you can see up close during the visit. The easy access and scenic lighting make this a visually stunning experience, as noted by previous visitors.
