The mystical Devil’s Throat Cave is located 1.5km away from Trigrad village, in the marble rocks of the famous Trigrad gorge.

The gorge is situated along Trigradska river basin, encompassed by magnificent in shape and size rocks. It is an area under protection. At some places the distance between the two banks is 300m, but at the very gorge they are 100m from each other. The West bank rocks are 180m high, as the East banks they reach 300 – 350m height. These vertical sizes make the Trigrad gorge third in Bulgaria, coming to size.

The first attempt to enter the cave is made in 1962. The cave is an abyss, created 175 000 years ago following the natural process of earth sinking as a huge tectonic opening has taken course. The waters of the Trigrad river are going down the gorge, falling from 42m rock, forming the highest underground waterfall on the Balkans. Because of the thundering noise, the cave’s main hall with the waterfall is called also “The Thunder hall” (Buchashtata zala). The cave is the second largest in Bulgaria. RIt is 110m long, 40m wide and its height comes up ti 35m.  400 meters from the entrance the water disappears down a sump, more than 150 meters deep, and when it emerges from the funnel into another cavern about 60 meters long, the underground river exits the cave and flows out among the mountain peaks through another cave.

The tour begins in an artificial gallery that leads visitors along the waterfall into the “Hall of Thunder.” There are 301 breathtaking steps descending alongside the thundering waterfall. The view of the roaring water and the enormous space of the cavern below are truly impressive. There are three impressive man-made sculptures. The first is at the cave’s entrance and resembles a devil’s head, and down its throat rushes a massive waterfall that from ancient times has captivated imaginations and given birth to numerous legends. The second is a man’s figure, carved in the stone of the Buchashtata Zala. There is a small spring with a tiny altar with Holy Virgin on it.

An interesting fact about the cave is that nothing carried into The Devil’s Mouth Cave by the river emerges from it. Many attempts have been made to track pieces of wood and other material through the cave, but they all vanish without a trace on the underground river, arousing curiosity and tantalizing the imagination. Experiments performed with dyes have shown that it takes more than 1, 5 hours for the water to traverse the short distance from one opening to the next, fueling speculations about an extensive system of underground streams in the cave.

Devil’s Throat cave and the Trigrad gorge are listed in the 100 Tourist Sites in Bulgaria with number 88.
