Vodnite Dupki (water halls) cave
ABOUT THE CAVE
The cave is located to the south-east of Pleven hut, along the northern slope of the massif of the peak of Botev. The first study and mapping of Vodnite Dupki was carried out in 1961. In 1982 it was studied and mapped in detail by the Caving Club Studenets (Pleven). Its altitude is 1400 m. Its total length is 813 m, and the displacement - 2 м / + 15 m. It is formed in Triassic limestone and develops along two main screes. The cave has two entrances located above each other. The upper is dry and from the lower one and underground stream flows out. The galleries starting from the two entrances join in the inner sections of the cave. Mainly primary karst forms could be observed – screes, denudation levels, blockages and individual gravity blocks, while the secondary ones are represented only by dendrites. The temperature of the underground river is 5oС.
Vodnite Dupki is cave, quite rich in inhabitants – troglobiont beetles and pseudoscorpions, some species of caddis flies and diurnal butterflies also find shelter from the unfavorable conditions there. It is a favorite place for a number of bat species. Sometimes even a bear could pick it up for wintering den. In terms of the bats, the cave is used for breeding and wintering of both typical cave dwelling species and from typical forest ones. For example such are the globally threatened Schreiber's bat, large mouse-eared bat, greater horseshoe bat, Mediterranean horseshoe bat and lesser horseshoe bat, Geoffroy's bat, barbastelle, Bechstein's bat. So far 17 species of bats are established which have been using the cave in different ways (for breeding, wintering, feeding, communication and rest), which makes it an unique place of bat importance into the Central Balkan National Park.
Despite that one of its entrances is seen, in winter the access to the cave hides avalanche hazard. Because of the cave’s extreme conservation significance, as well as its location within Severen Dzhendem Reserve in the Central Balkan National Park, the penetration is prohibited, if this is needed for research purposes permissions should be obtained from the MOEW and the National Park Directorate.
