Kostanjevica cave opens over the source of the Studena spring and is situated in the direct vicinity of Kostanjevica na Krki, at the foot of the Gorjanci Hills. Because of the cave’s proximity to the town, you can take a walk to get there. Join guided tours from April to October and discover its fairy-tale beautiful limestone formations created through millennia. In front of the cave, there is a cavers centre and a large meadow with a stream, which is a popular picnic place.
