About the Cave
A fantastic web of tunnels, passages, galleries and halls,
the astonishing diversity of Karst features as well as easy
access are certainly the main reasons for such popularity
of the cave and a large number of visitors, which has
already reached 34 million in 200 years.
Postojna Cave is the best-known cave in the world. It is
also the greatest tourist attraction in Slovenia and one of
the world's largest karst monuments. Many books and
other contributions have been written about Postojna
Cave; speaking of tourist guides regarding the cave itself,
almost 100 have been produced over 200 years.
