The Belogradchik Rocks (Bulgarian: Белоградчишки скали, Belogradchishki skali) are a group of strange 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 for 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.
