Perperikon is situated in the Eastern Rhodopes, some 15 km from the town of Kurdjali. It is towering from a rocky peak at a height of 470 m.
The auriferous Perperishka River flows by the village of Gorna krepost, which is located at the foot of Perperikon. The comfortable river valley with a length of 10 km and width of 4 km has created excellent living conditions since ancient times. That is why there are dozens of archaelogical sites of different ages present here, whose centre turns to be Perperikon.
Perperishka River flows into the artificial lake Studen kladenets, built by the river bed of Arda River. The influx at the vilage of Kaloyantsi is very picturesue and was built-up as a mountain resort.
