Just a short walk from Krumperk Castle, Železna Jama cave is yet another in Slovenia’s long line of fascinating caves. Well lit inside, the cave sits comfortably at a temperature of 8 degrees and is full of rich stalactites and interesting formations. The first of these you notice is the strangely Camel’s head shape jutting out over the walkway deeper into the cave. The natural acoustics are wonderful, and choirs have been known to perform in the cave from time to time. Adjoining Železna Jama is Babja Cave, but this currently isn’t open to visitors.
The Jamarski museum near the entrance to the cave is choc-full of minerals, fossils and stalactites from not only Železna Jama but also caves from all over the country. Impressively the museum is home to the nation’s biggest collection of stalactites, moved from the Natural History Museum in Ljubljana after being damaged in a fire. The house also runs a caving club for children.
