Aiguille de Borderan, Mountain summit in Savoie, France

Aiguille de Borderan is a 2,492 m summit on the border of Savoie and Haute-Savoie in the Aravis Massif. Its upper part is bare pale grey sedimentary rock split by dark crevices and vertical gullies, with angular ridges running down. Green grass covers the left flank and lower slopes, and a band of dark coniferous forest lies across the base and lower right.

The Aiguille de Borderan is a summit of the Aravis chain reaching 2,492 m, standing on the boundary between the Savoie and Haute-Savoie departments. Its pale grey sedimentary rock, split by dark crevices and vertical gullies, is the limestone of the Aravis Massif, laid down in a former sea and later raised and carved by glacial and water erosion. The surrounding meadows have long served alpine communities for summer grazing.

The summit sits on the border between Savoie and Haute-Savoie, and the slopes below it belong to the alpine pastures of the Aravis. In summer, cattle from valley farms are driven up to graze these high meadows, and the milk is turned into Beaufort and Tomme cheeses in the surrounding dairies. Walkers on the trails hear cowbells and pass stone farm buildings still used for the summer season.

Visitors planning to climb should bring proper equipment and check weather conditions before heading out, as alpine conditions can shift rapidly throughout the year. Starting early in the day helps make best use of daylight and reduces exposure to afternoon storms that are common in this region.

The Aiguille de Borderan is a launch site for paragliders, not skydivers: pilots run off the slope with an open wing already above them. The summit stands at 2,492 m on the ridge between Savoie and Haute-Savoie, and the ski-lift pole with a yellow sign visible at its base belongs to the surrounding ski area.
