Bacho Kiro cave is a four-level karst system located in the foothills of the Balkan Mountains near Dryanovo, Bulgaria. It is recognized as one of the most important archaeological sites in the region, featuring remains of Homo sapiens dating back to approximately 46,000 years ago. The cave spans over 3,600 meters of total passages, with specific routes designated for tourists. Visitors can observe distinct rock formations including stalactites, stalagmites, and stone curtains formed through continuous water filtration. The cave system is situated in the canyon of the Dryanovo River. It serves as a significant site for both geological study and paleoanthropological research. Several subterranean galleries are accessible to the public, featuring narrow corridors and high chambers. The environment maintains a constant year-round temperature, providing a stable microclimate for local bat colonies.
