Lago Agnel, Alpine reservoir in Ceresole Reale, Italy

Lago Agnel is an alpine reservoir nestled in a mountain valley at about 2300 meters elevation, holding water in an artificial basin created by a dam. The water supply serves both hydroelectric purposes and local communities in the region.

Agnel Lake is one of the artificial lakes of the Orco valley, together with Serrù Lake, Ceresole Lake, Piantonetto Lake and Valsoera Lake, whose water feeds several hydroelectric power stations. A man-made channel starting from Agnel connects it to Serrù Lake and Ceresole Lake. The lake lies within the Gran Paradiso National Park, along the road from Ceresole Reale to the Nivolet Pass.

The lake became known worldwide after appearing in a famous heist film from the late 1960s. Visitors often recognize the mountain setting from this well-known movie.

The lake can be reached by road from Ceresole Reale and is accessible year-round, though access may be limited on some summer weekends. Visitors should prepare for cold weather and mountainous terrain with appropriate clothing and gear.

A man-made channel starting at Agnel links it to Serrù Lake and Ceresole Lake, part of a chain of artificial basins feeding hydroelectric plants. The lake lies within Gran Paradiso National Park, and in 1969 its shore served as the setting for the final scene of the film Un colpo all'italiana.
