The Bacho Kiro Cave is located near the Dryanovo monastery. It is also known as the Dryanovo Cave and was opened in 1890 and since 1964 it has been electrified. For as long as 1200 m a fairytale underground world reveals itself to the eyes of the visitor. The formations follow one after another - “Bacho Kiro’s Throne”, “the Dwarfs”, “The Sleeping Princess”. The “Throne Hall”, the “Reception Hall”, the “Haidouti Meeting-Ground”, the “Fountain”, the Sacrificial Altar” evoke the admiration of the visitors. Remnants of people who lived during the Paleolithic Age were found in the cave.
