Gran Truc, Mountain peak in Piedmont, Italy.

Gran Truc is a 2,366-metre summit in the Monginevro Alps, in the Cozie Alps, on the border between the Germanasca and Chisone valleys in the province of Turin. It stands at the head of the Angrogna valley, a side valley of the Pellice, and three ridges branch off from the top: one runs east to the Colle della Vaccera, one north to the Colle Lazzarà, and one south-west towards Punta Lausarot, Punta Cialancia and Punta Cornour. A white metal cross, a lightning rod and an Arpa Piemonte weather station stand on the summit.

The Gran Truc, 2,366 m, connects the so-called Valli Valdesi and in the past served as a refuge for Waldensian bandits and rebels. It lies between Val Germanasca and Val Chisone, at the head of the Val d'Angrogna, a side valley of the Val Pellice.

The mountain marks the meeting point of the so-called "Waldensian Valleys" and in the past served as a refuge for Waldensian bandits and rebels. The summit cross, lightning rod and weather station of Arpa Piemonte stand on top.

Climbing this peak requires proper mountain gear and alpine climbing experience, particularly during winter when snow and ice cover the routes. Plan adequate time for the ascent and check weather forecasts before departing, as conditions change rapidly at elevation.

The summit carries a white metal cross, a lightning rod and a weather station of Arpa Piemonte, the regional environmental agency. The station is part of the network monitoring the Alpine environment, so the peak doubles as a measuring point above the Val d'Angrogna.
