About Postojna Cave

Postojna Cave is a sprawling underground labyrinth that stretches for over 24 kilometers, making it one of the longest cave systems in the world.

Today, it serves as both a major tourist attraction and an active research site for speleologists studying karst geology.

The cave maintains a constant temperature of 8°C (46°F) year-round, creating a unique microclimate that supports rare species of cave-dwelling creatures, including the famous olm or 'human fish' – a translucent amphibian found nowhere else on Earth.
