The Orlova Chuka cave is located on the right side of the Cherni Lom river valley. It is a geological formation most likely to have appeared at the end of the Pliocene and the beginning of the Quaternary, on the riverbed of an underground river, which has dug a complex system of tunnels, passages and openings. The cave has a total length of almost 13.5 km, thus being the second largest in Bulgaria, after the Duhlata cave. It was discovered in 1941 by a shepherd from the area, and has been open to the public since 1957. The cave is divided into several rooms: Concert Hall, Great Gallery, Great Groots, Little Groots, Space Hall and Rest. The cave offers visitors the opportunity to admire a wide variety of rock formations. When researched by specialists, remains of bears and artifacts from the life of cave people were found here. At the same time, the cave is home to 14 species of bats, three of which are included in the Red Book.
