The cave serves as a habitat for several protected species of bats, including the Lesser Horseshoe and Greater Horseshoe bats.
Objects entering the underground river at the cave's entrance have never been recovered, proving the river disappears into an unexplored, impassable siphon.
The cave is linked to the ancient Greek myth of Orpheus, who is said to have descended here to find his wife, Eurydice, in the underworld.
The temperature inside the cave remains constant at approximately 8 degrees Celsius year-round.
The underground river that traverses the cave re-emerges to the surface hundreds of meters downstream.
The volume of the underground hall is so vast that it can accommodate a 15-story building.
Devil's Throat Cave is an abyss-type cave located in the Western Rhodope Mountains of Bulgaria, formed by the collapse of a riverbed. It is famous for housing one of the highest underground waterfalls in the Balkans, which plunges 42 meters into a large cavern hall. The cave acts as a sinkhole for the Trigrad River, which enters the mountain through a massive vertical entrance and disappears into a siphon. Visitors enter through a man-made tunnel and ascend a steep staircase located directly alongside the roar of the subterranean waterfall. The cave is part of a karst system and is geologically categorized as a 'young' cave structure. It lacks traditional stalactites and stalagmites due to its rapid formation and the intense flow of water. The cave's main chamber, known as the 'Roaring Hall', measures 110 meters long and 40 meters wide.
The viewing platform near the base of the waterfall, which captures the scale of the 42-meter drop.
Bring a sturdy jacket, as the humidity is near 100% and temperatures are chilly even in summer.
Wear shoes with excellent grip, as the stairs can be slippery from the constant spray of the waterfall.
Be prepared to climb over 300 steep steps; the route is physically demanding.
Avoid visiting in periods of heavy, prolonged rainfall, as the cave may close for safety reasons due to rising water levels.
Operations are highly weather-dependent; the cave may be closed during severe floods or heavy storm events.
Photography is generally permitted, but flash usage is often restricted to protect the resident bat population; follow guide instructions regarding silence.
