Mont Jalla, Limestone mountain peak in Isère, France
The 635-meter summit of Mont Jalla forms the southernmost extension of the Chartreuse massif, overlooking the urban area of Grenoble with its flat top.
From 1869 until the early 1900s, a cable car system transported limestone from Mont Jalla's summit to cement factories in the Porte de France district.
The national memorial for mountain troops established in 2000 at Mont Jalla honors the service members who protected French alpine territories.
Hikers can reach the summit through multiple routes, including a 30-minute walk from the cable car station or a longer trail from Col de Vence.
Mont Jalla contains 18 interconnected underground galleries, remnants of extensive limestone mining operations that supplied local cement production.

Around Grenoble, the mountains begin at the edge of the sidewalks. It only takes a few steps to leave the streets and reach a path that climbs toward the trees. Here, nature is never far away: it surrounds the city, observes it, invites it out. You climb the Bastille hill, cross the Chartreuse forests, follow the Isère river, or ascend toward the cliffs of the Petites Roches. The trails follow one another and are not alike: some are gentle, others more athletic, but all offer the same feeling of space and light. Between hikes, you discover parks, gorges, plateaus, and villages hanging over the valley. Grenoble lives to the rhythm of the seasons, hikers, and the wind in the pines. It is a city oriented towards the mountains, where each step takes you a little higher.
