The Bacho Kiro Cave is located 300 meters from the Dryanovo Monastery in a 25 meter limestone cliff. This is the first developed cave in Bulgaria (1937). Since 1940, it bears the name of Bacho Kiro, a revolutionary and participant in the April Uprising of 1876.
The cave is a complex labyrinth of galleries and branches, with a length of 3600 meters. Visitors are offered two routes. The first route is about 700 meters long and takes 70 minutes to complete, whereas the second shorter route takes about 30 minutes and is 350 meters.
For thousands of years rivers have sculpted these caverns and galleries in varied and interesting forms, as well as the classic forms (stalactites and stalagmites).
