Devil's Throat Waterfall, Underground waterfall in Rhodope Mountains, Bulgaria

Devil's Throat Waterfall is an underground cascade in the Rhodope Mountains that plunges into a vast cavern called the Roaring Hall. The chamber stretches roughly 110 meters long and 40 meters wide, creating a dramatic natural space within the mountain.

The cave and its waterfall are formed by the Trigradska River, which sinks underground and drops 42 m into the chamber called the Roaring Hall. That hall, 110 m long, 40 m wide and 35 m high, is Bulgaria's second-highest cave hall after the entrance hall of Devetashka Cave. The sources record no ancient rituals or Orpheus link here.

The hall where the waterfall falls is called "Buchashtata" (the Roaring One) because of the loud rumble of the water. It is the second-highest cave hall in Bulgaria after the entrance hall of Devetashka Cave, measuring 110 m long, 40 m wide and 35 m high.

The cave lies by the Trigradska River in Smolyan Province. The waterfall falls into the Roaring Hall, 110 m long, 40 m wide and 35 m high, the second-highest cave hall in Bulgaria after the entrance hall of Devetashka Cave. Expect loud noise from the falling water and a cool, damp interior; wear shoes suited to uneven, wet ground.

The waterfall drops 42 metres, making it the highest underground waterfall on the Balkan Peninsula. It falls into a hall 110 metres long, 40 metres wide and 35 metres high, the second-highest cave hall in Bulgaria after the entrance hall of Devetashka Cave.
