The Rhodopes are a mountain range in Southeastern Europe, with over 83% of its area in southern Bulgaria and the remainder in Greece. Its highest peak, Golyam Perelik(2,191 m), is the seventh highest Bulgarian mountain. The region is particularly notable for the Karst areas with their deep river gorges, large caves and specific sculptured forms, such as the Trigrad Gorge.
A significant part of Bulgaria's hydro power resources is located in the western areas of the range. There are a number of hydro-cascades and dams used for electricity production, irrigation and as tourist destinations. The Rhodopes have a rich cultural heritage including ancient Thracian sites such as Perperikon, Tatul and Belintash; medieval castles, churches, monasteries and picturesque villages with traditional Bulgarian architecture from 18th and 19th century
