Sport Via Ferrata: la Tour du Jallouvre Le Grand-Bornand


Departing from Le Grand-Bornand (74450)
Average length : 05h00
Distance : 1.1km

After a 20 to 30 minute approach from the parking lot, start up the first section by traversing a series of ledges up and left, over good quality rock, that lead to “Arche du Bouquetin” (Ibex Arch), just prior to the crux of the route. Climb up and over the slightly overhanging crux via a series of small steps, which require moves similar to climbing. This overhanging section is called the “Cul Tourné”, French for “turning your rear end around”. After a section over rock, then another easy section, traverse directly towards “La Tour” (TheTower).
You can stop here, and start your descent via the “Sortie à Fred” (Fred’s Exit), by walking along an easy ledge, and then down a few steps to the descent trail.
Reach the tower via a 16 m long hanging footbridge (the “Passeralle du Gypaète” or “Bearded Vulture footbridge”, there are bearded vultures in the area). Enjoy the exposure when crossing the footbridge and then start climbing up the impressive pillar overhead. A long traverse across the rocky face followed by another hanging footbridge will be an exciting experience to say the least. One more easy section up a beautiful arête and you’ve reach the top of the tower.
The descent starts via a long traverse across Jalouvre’s upper face until you reach a steep couloir equipped with cables, bringing you to Col du Rasoir pass and a well used hiking trail. (Often snow here at the beginning of the season).

DIFFICULTY: this route is fairly long and committing, especially once beyond the hanging footbridge. The descent can also be more challenging at the beginning of the season when there may still be snow.
