The cave can be found along an alternate road from Sofia to Bucharest and is way more impressive in real life. Why ? Well the photo’s don’t do it justice, but take a look at the man and that hut. The cave reaches 100m in height in some places and it’s one of the largest in Europe.
From the top it just looks like your regular hills covered with trees and grass. Until you make a wrong step .
One of the most spectacular places in Bulgaria.
