Kostanjeviška jama

In 1937 a rapid increase of the subterranean water fractured the rock and opened a natural entry for the people of surrounding villages. In 1971 lightning installation was made and 300m of main attractions were offered to tourists. The length of the cave is a bit more than 2 kilometers but cavers are still exploring the enter cave system.
The photos in the cave are suitable for children as well as old visitors. A guided tour with explanation lasts 40 minutes. The constant temperature in the cave is 12 degrees celisius. Kostanjevica cave lies at the foot of the Gorjanci Hills, a Diverse Karst Terrain with Cretaceous Limestone. Rain water, subterranean watercourses and tectonic movements spent millennia creating dreamlike cave formations with fairytale motifs.
