Col de l'Arc (1854 m) walks

Ascent of Bellacha via a wild trail on the way up, following the north-west and north ridges of Bellachat. The return route is via the Col de l'Arc and Col de Basmont passes, which offer different landscapes and avoid the descent via the ascent route, which is not always easy to find. This loop is not recommended in the opposite direction.

A change of scenery: the view opens out towards the Beaufortain, the Tarentaise, the Aravis and then the Vanoise. You pass beneath the Grand Arc, descend towards the Vallon de Bayet, cross the Col Basmont, then spend the night at the Col de l’Arc in the unmanned hut

It’s hard to say much about this section, as we completed the whole of it in driving rain and cloud. The route is challenging and stony, with numerous herds of livestock and detours… But it remains so beautiful despite everything. The climb up the Bellachat is less difficult than it looks. The landscape is actually very varied: there’s a lot of rocky terrain on the ascent of the Bellachat, with steep cirques all the way to the Lacs du Loup, where the mountain pastures take over before giving way to the Cirque du Colomban, only to return near the Refuge du Logis des Fées.

This small mountain range undoubtedly offers one of the most stunning sequences of panoramic views. But beware of the challenging paths and the isolation. Pay particular attention to water management: streams and springs often run dry in summer.The starting point is Saint-François-Longchamp, accessible by public transport or by road. Parking is easy and free there in summer. The stages are connecting days. This route follows the Tour de la Lauzière route with a detour via La Thuile and the Col de l’Arc. You’ll spend every other night in a refuge and the rest in a bivouac.Do not attempt this hike if you are not sure-footed: although it stays on the paths (or strays very little from them), this route requires vigilance and follows routes that are very rarely used. You will almost certainly find yourself alone, or almost alone, for most of the day, in conditions where the markings are often half-faded and the paths obscured by livestock tracks. High-altitude cloud cover is common.
