Orlova Chuka is located on the picturesque left slope of Cherni Lom River, 2.5 km northeast of Pepelina Village and 7 km east of the town of Dve Mogili. In 1959, 124 stone steps were built in Orlova Chuka and an artificial tunnel was drilled to serve as entrance. The cave is the second longest improved cave in Bulgaria. Its name is related to the rock crown on which its entrance is located. In the recent past, this crown served as a refuge for eagles. The biggest contributions for the comprehensive study of the northeastern part of the Orlova Chuka were provided by Ruse cavers. To them the giant labyrinth of Orlova Chuka Cave is almost a constant subject of study. The Orlova Chuka Cave consists of a very complicated system of cave tunnels, large and small halls. With its 13.5 km of explored and mapped galleries, it ranks second among Bulgaria's longest caves. The place allows for rock climbing competitions, orienteering and specific cave events to take place. A national cave gathering is held here every year in April.
