Located 11 km east of the town of Dve Mogili and 3 km north of the village of Pepelina in the rocky gorge of the Cherni Lom River is "Orlova Chuka" - one of the most interesting caves in Bulgaria. It has been declared a natural landmark since 1963 and since 1978 - an archaeological monument of culture of national importance. The cave's name is associated with that of the rocky ridge on which its entrance is located. In the recent past, this ridge was a refuge for eagles.
The cave was formed in Cretaceous limestones deposited at the bottom of the former Sarmatian Sea. The cave galleries were formed much later as a result of karst processes that occurred during the Quaternary. The skeletons of bears, spearheads, flint scrapers, an axe, and fragments of clay vessels from the Eneolithic era (the Stone-Copper Age) indicate that the cave was inhabited by humans (200,000 - 40,000 years BC). The total length of the cave galleries has been established - over 13,500 m. These figures rank the cave second in length in Bulgaria, after the "Duhlata" cave.

The cave is inhabited by more than 10,000 bats. These cave flying mice are of three species - the common squeaky bat, unique for Europe, and the large and small horseshoe bat. There is a hut built next to the "Orlova Chuka" cave. It is a massive two-story building, water-supplied and electrified, which provides shelter for 27 people. There is a kitchen and a dining room with a fireplace, outdoor toilets, indoor and outdoor fountains, and a bathroom.
