Kostanjevica Cave

The easily accessible Kostanjevica Cave is the largest Karst cave in the Dolenjska Region, with lesser caverns, potholes, swallow holes, and springs. This is one of the most beautiful caves in Slovania.

The Gorjanci Hills, a complex karst environment with cretaceous limestone, are home to Kostanjevica Cave. Rainwater, underground watercourses, and tectonic movements have carved out surreal cave formations with fairytale themes over millennia.

A fast rise of subsurface water cracked the rock in 1937, creating a natural entry for residents of the nearby villages. In 1971, a lightning installation was completed, and tourists were given access to 300 meters of the principal features. The cave is slightly longer than 2 kilometers in length, although cavers are currently investigating the full cave system.

The cave's walkways are suited for both children and older tourists. A 40-minute guided tour with explanation is available. The cave maintains a constant temperature of 12 degrees Celsius.

Length: over 2,000 m
