About Lake Sibinacocha
Lake Sibinacocha is a high-altitude glacial lake in the Vilcanota mountain range of the Department of Cusco, Peru. It is one of the larger high-mountain lakes in the region and lies among glaciated Andean peaks.
The lake is elongated and surrounded by alpine terrain used by trekkers and mountaineers accessing nearby peaks, including Ausangate. Its remote setting and elevation make it an important feature of the local high-Andean watershed.
The basin is glacial in origin and the lake occupies a valley carved and filled by glacial and meltwater processes over the late Pleistocene and Holocene. Local communities and downstream water systems are influenced by its seasonal and long-term water balance.
The lake sits in the high Andes of southeastern Peru within the Vilcanota range, in the broader Cusco region.
- High Andean location: Sits high in the Vilcanota (Cordillera Vilcanota) range of the Andes, near major peaks such as Ausangate; the lake is notable for its high elevation.
