It is the most significant glacial cirque of the Sierra de Gredos, and of the entire Sistema Central, approximately 33 hectares (330,000 square meters) in area. At the East edge of the cirque is the summit Pico Almanzor, the highest of the range at 2,592 meters. At the northeast edge, the bottom of the cirque, is the Laguna Grande de Gredos at a height of 1,940 metres. Next to this lake is the mountain refuge Elola, much frequented by mountaineers who intend to climb Pico Almanzor. The cirque is in the basin of the river Tormes, a tributary of the river Duero. It is part of the Sierra de Gredos Regional Park.
