About this activity

So, how is it possible that Lake Cerknica disappears all of a sudden? Is it physics or is it magic? Wait ‘til we get to the lake, hear the story of witch Uršula, and decide for yourself. Magical spirit of legends will follow us to the most known of Slovenia’s sights, Postojna Cave.

This Karst cave system of monumental passages, a Concert hall with exquisite acoustics, an intriguing Spaghetti hall, are all a home to endemic olm - proteus anguinus. Who or what is Proteus anguinus? A rather non-explicable species, which you simply have to see. You’ll conclude this memorable and grandiose exploration with a visit to Predjama castle, where you will hear the story of the castle’s lord Erazem and his interesting life.
