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 west edge of the cirque is the summit Pico Almanzor, the highest of the range at 2,592 meters.

In the northeast, at the bottom of the cirque, is the Laguna Grande de Gredos at a height of 1,940 metres.

The well defined route climbs South-West from here, and then across a grassy boggy moor to arrive at the Barrerones (2,210 metres).

From here, the path descends south until reaching the Laguna Grande (or great lake) de Gredos.
