The Iezer-Păpușa Mountains stretch between the rivers Dâmbovița to the east and the Doamnei River to the west. In the area where they spring is the Mezea-Oticu peak, the peak through which the Iezer-Păpușa Mountains communicate with the Făgăraș Mountains.
In the inner part of the massif there is the Râușor Dam, behind which the Râușor Reservoir was formed, fed by Râușor and the Târgului River.
At an altitude of 2135 meters, below the peak of Iezerul Mare, inside the massif is Lake Iezeru Mare, a glacial lake located in a cauldron guarded by bare and wild peaks.
Optional trips to this destination can only be arranged in July, August and September.
