Lac de Nino, Glacial lake in Haute-Corse, France.

Lac de Nino is a glacial lake high in the Corsican mountains at about 1,743 meters elevation, covering roughly 0.065 square kilometers with a maximum depth of 12 meters. The water sits in a mountain basin surrounded by green meadows interrupted by small water-filled depressions.

Lac de Nino is a glacial lake at 1,743 m, its basin ringed by old moraines. It lies on the plateau du Camputile, on the GR20 between the communes of Corte and Casamaccioli, and collects the headwaters of the Tavignano, Corsica's second river by length and flow.

Shepherds have traditionally used the meadows around the lake to graze their herds, and wild horses roam freely among the pozzines that mark the landscape. This long-standing practice continues to shape how the area looks and functions today.

The lake can be reached from several hiking trails, including the famous GR20 long-distance path, with the main approach via the Vergio mountain pass. The best time to visit is during the warmer months when the trail is clear and the meadows are green.

The lake is the second-largest in Corsica at 6.5 hectares, and it stays frozen for five to six months a year. It lies at 1,743 metres on the Camputile plateau and forms the source basin of the Tavignano, Corsica's second river by length and flow. Old moraines ring the water, and a fen with meandering meltwater channels borders the northern shore.
