Before entering the Trigrad Gorge, the Trigradska River falls into the Dyavolskoto Gurlo (Devil’s Throat) - a fantastic cave, where, along the following 7000 metres, the water forms some 18 waterfalls and passing through the enormous Roaring Hall exits into the canyon. This miracle of nature is electrified and can be visited against a symbolic fee.
