The Smolyan Lakes (Bulgarian: Смолянските езера) are located in the Bukova Mountains, Western Rhodopes, north of the Orpheus Rocks and Snezhanka Peak. They are scattered along the left slope of the Cherna River valley to the town of Smolyan. They were formed by a large landslide that occurred as a result of contact between rhyolitic rocks and water-resistant sedimentary rocks located below them. In the past there were more than twenty lakes, but now there are only 8 left, the others today are swamps.
