Signal of Iseran, Mountain summit in Savoie, France

Signal of Iseran is a mountain peak reaching 3237 meters in the Graian Alps, positioned between the Maurienne and Tarentaise valleys. From the summit, visitors can see across multiple surrounding mountain ranges and the broader Alpine landscape.

The summit lies on the boundary between the Maurienne and Tarentaise valleys, above the Col de l'Iseran. The pass below, at 2,764 metres, is the highest paved mountain pass in the Alps. The mountain is part of the Levanne-Aiguille Rousse chain in the Graian Alps, and its slopes now host part of Val-d'Isère's ski area, including summer skiing on the Grand Pisaillas glacier.

The summit stands on the municipal boundary between Bonneval-sur-Arc and Val-d'Isère, above the Iseran pass. At its feet lies part of the Val-d'Isère ski area: the Iseran valley to the west and the Grand Pisaillas glacier to the south-east, where summer skiing takes place. The Italian name Signal du Mont Iseran is also used.

The summit stands 473 metres above the Col de l'Iseran (2764 m), which lies immediately to its south-west and is reached by road. The mountain sits on the boundary of Bonneval-sur-Arc and Val-d'Isère, with the Val-d'Isère ski area at its foot in the Iseran valley to the west and on the Grand Pisaillas glacier to the south-east, where summer skiing takes place. Approach from one of these sides; the upper slopes are bare fractured rock and scree, with snow patches lingering on the north-east face.
