Mont Granier

Mont Granier is a limestone mountain in the Chartreuse range rising to 1,933 meters, with a vertical rock face reaching about 900 meters high. The southern side displays massive limestone layers that give the peak its distinctive appearance.

The mountain served as a triangulation station in early surveying systems used to map the region. In 1248, a catastrophic landslide destroyed several villages when a massive limestone mass collapsed on the slopes.

The slopes support vineyards producing local Apremont and Abymes wines using the Jacquère grape variety grown here for centuries. This wine tradition shapes daily life and local identity in the villages below.

Multiple hiking trails start from the village and lead to the summit with varying difficulty levels for different abilities. The climb requires sturdy footwear and sure footing, especially on steeper sections with rocky ridges.

An extensive cave system lies beneath the mountain with hundreds of underground chambers yet to be fully explored. The Balme-à-Collomb cave preserves remains of prehistoric cave bears that died here thousands of years ago.
