Devil’s throat
The Devil's throat is a gorge cave, which was formed after the collapse of earth layers. The cave is situated 1.5 km north of the village of Trigrad in the Trigrad gorge in the Rodopi mountain. Its main part is occupied by a big hall, where the highest underground waterfall on the Balkan penincular is situated.
The cave has been formed from a river, which flew underground from 42 m of height, forming a large hall called Buchashta (Thunder) hall. Its length is 110 m, its width - 40 m and its height reaches up to 35 metres.
This is the biggest hall in the Bulgarian caves after the entrance hall of the Devetashka cave - the ‘St. Aleksander Nevski' could fit in there. The entrance to the cave is an artificial hall 150 m in length, through which people reach the basis of the water flow. 301 steps from here lead along the underground waterfall through the old entrance and on the surface.
Nearly 400 m from the entrance of the ‘Devil's throat' the waters of the underground water pass into a siphon-gallery. The length of the siphon is 150 m and sfter it on a 60-metre gallery the underground river leaves the cave and flows on the surface again.
The largest in Bulgaria and on the Balkan penincular colonies of cave bats with long wings hibernates in the cave.
The cave is among the hundred national tourist destinations of the Bulgarian tourist union.
