Caves - Zadanenka | Lukovit - Natural Sights

A cave near the village of Karlukovo. Its denomination is probably given by the local population because of some of its dead-end entrances or by the name of the gorge. It is located in western direction from the village, low on the right bank of Zadanen dol. Big branched one-stage cave shaped from running water in the failure of the upper stratum by the limestone from the Maastrichtian Stage. Its length exceeds 1200 m. It is not fully researched yet. You enter in it through a low narrow gallery. From the beginning it is high and accessible despite the two abysses of 18 m. but after you pass by the small muddy lake it slopes down and becomes narrow. You crawl over soft clay about 1000 m. 200 m before the end of that dark gallery you have to overcome a threshold of three meters. You reach a vertical cleft but that is not the end of the cave. It is followed by a diversion to the right, a thick layer of clay and a muddy lake. It has not been ascertained till what point the cave goes. The presence of water and alimentary substances that had come from the clay of the plateau create conditions for living in darkness of 19 species of organisms among which are sideways floating crab, cave centipede etc. It is accessible for visitors but only experienced and well-equipped speleologists on cloudless days.
