Krizna Jama is the subterranean bed of a river and is famous for its 22 lakes and the beautiful speleothems. Also the remains of more than 100 cave bears were found near the entrace. Some of them are now shown in the Vienna Natural Science Museum.

Visits are only possible in times of low water table. All the necessary equipment for viewing the cave's 22 lakes is made available by the guides. For the first part, no special equipment is needed. It is possible to tour only this part, called tourist trip. It still requires a short boat ride. For the wet tour wellington boots, caving suits, battery lights and inflatable boats are essential. This tour shows 13 lakes and ends at the calvary, a huge pile of debris covered by stalagmites.
