Devil's Throat Cave
Devil's Throat Cave (Dyavolskoto Garlo) is a terrifying natural karst cavern located within the sheer vertical marble walls of Trigrad Gorge in the Western Rhodope Mountains of Bulgaria. Known since antiquity as an entrance to the Underworld, the cave features an enormous subterranean waterfall that plunges 42 metres into a roaring cavern known as the Hall of Thunder. The site is legendary for its refusal to yield anything swept into its underground river: logs, boats, and dyes vanished without a trace, and two professional Bulgarian cave divers lost their lives in 1970 trying to explore its mysterious underwater sumps.
