The Belogradchik Rocks (, Belogradchishki skali) are a group of strangely shaped sandstone and conglomerate rock formations located on the western slopes of the Balkan Mountains (Stara Planina) near the town of Belogradchik in northwest Bulgaria. The rocks vary in color from primarily red to yellow; some of the rocks reach up to 200 m in height. Many rocks have fantastic shapes and are associated with interesting legends. They are often named after people or objects they are thought to resemble. The Belogradchik Rocks have been declared a Natural Landmark by the Bulgarian government and are a major tourist attraction in the region. They are the only habitat of the critically endangered Bulgarian endemic plant Hieracium belogradcense.

The fifth group of rocks lies between the villages of Gyurgich and Belotintsi. Geology Many rock figures and small valleys with steep vertical slopes have formed over hundreds of millions of years as a result of the natural processes of erosion, denudation, growth of mosses and lichens, and other natural factors. The formation of the Belogradchik Rocks started during the Permian period, about 230 million years ago, when the tectonic cycle was folding to create the Balkan Mountains and elevating the region of Belogradchik. Later, during the Triassic period, the region became the floor of a shallow sea. At
