Krizna Jama is huge! Basically, it consists of a main river passage with 22 lakes ending at Kristalna Gora (Crystal Mountain). At the far side of the first lake, is Medvedji Rov (Bear Passage), which has quite a collection of fossils of the extinct cave bear. Apparently they all died of starvation during hibernation.

We paddled along the gallery in inflatable dinghies, stopping only to cross the calcite dams between the lakes. Many large formations were passed including all the usual stuff - columns, curtains and flowstone. At Kalvarija, the mid point, we were faced with a row of 20' high columns across the entire width of the passage - what a sight. From here, a scramble up some boulders led into the roof above Kalvarija where an amazing display of flowstone and straws lay before us.

Further upstream on the right is Matjazev Rov, a passage with magnificent formations, but the best part of the cave is, by far, Kristalna Gora - at the end of the main passage - with it's crystal embedded stal.
