The traditional normal route, now mainly used as the descent from the Forbes Arête: from the Refuge Albert 1er across the crevassed Glacier du Tour to the Glacier de l'Épaule, up an enclosed couloir (rappels on descent) to the snow saddle by the Aiguille Adams Reilly, then mixed ground, a snow slope to the fore-summit (3,800 m) and a narrow, corniced ridge to the top.

About 50% of this line is approximate (no mapped trail; drawn from the terrain). Check it against a map before relying on it.

From Le Tour (1,480 m) above Argentière, walk or take the gondola to Charamillon (1,854 m) and follow the easy path to the Refuge Albert 1er (2,707 m) on the north bank of the Glacier du Tour: about 3 hours from the village (FFCAM) or 2¼ hours from the top of the lifts (SAC). From the hut follow the route towards the Col du Tour and, just below the col, traverse the Glacier du Tour level towards the Aiguille du Chardonnet to reach the Glacier de l'Épaule (about 2 hours; many large crevasses). Climb the Glacier de l'Épaule towards the Col Supérieur Adams Reilly, leaving the Épaule (3,587 m) on the right, and go up the enclosed couloir that is used for the rappels on descent (stonefall if parties are above). Exit onto the snowy saddle between the Chardonnet and the Aiguille Adams Reilly, climb it on the right to the mixed ridge, then the snow slope to the fore-summit (3,800 m). Follow the fine summit ridge east to the top, watching for cornices. Allow 5–6 hours from the start of the climb. Descend the same way in 2–3 hours: down-climb a short steeper step between rocks to two 20 m rappels in and below the couloir, then the Glacier de l'Épaule and the Glacier du Tour. If the bergschrunds are too open, a newer line of rappels on the spur between the Charlet-Bettembourg gully and the normal route is used. The SAC warns that even the easiest descent on this mountain can be problematic.

Overview

A 3,824 m granite and ice peak dominating the Glacier du Tour basin above Le Tour, near the Swiss border. Best known for the Forbes Arête (AD), one of the classic mixed ridges of the Alps; the old normal route (AD-) is now mainly the descent.

The Aiguille du Chardonnet is the highest point of the long ridge separating the Le Tour and Argentière glacier basins, with the Swiss border running just east of the summit. Its summit ridge is about 800 m long, jagged and gently inclined: from Pt. 3680 in the east (the Forbes Arête) over the main summit to the Épaule (3,587 m) in the west. The north side is snow and ice with a range of gullies and buttresses; the south side is an 800 m wall of spires and towers above the Argentière glacier.

The SAC describes it as one of the most imposing summits of the Alps and warns that every approach is difficult, and that even the easiest descent can be problematic. Most climbers come for the Forbes Arête, a long mixed ridge climb from the Refuge Albert 1er that is busy on fine weekends; the traditional normal route by the west ridge is used to descend.

There is no easy way up: all routes involve crevassed glaciers, steep snow or ice, and rappels in descent.

Climbing Notes

You need sound glacier and crevasse-rescue skills, confidence on 45–55° snow and ice, competence on exposed mixed ridges to about III, and fluent rappelling; plus fitness for a 10–12 hour day from the hut. Many parties climb with a guide from Chamonix, Argentière or Trient.

Typical itinerary: day one, Le Tour to the Refuge Albert 1er (about 3 hours on foot, less with the Charamillon gondola); day two, the Forbes Arête or the normal route and descent to the hut or valley. From Switzerland, the Cabane du Trient is the base, reached via the Col du Tour. The Forbes Arête faces east: start early, and leave enough time for the descent before afternoon stonefall. Late in the season La Bosse and the descent couloir become icy and the bergschrunds open; a newer rappel line exists for that case.

Bivouacking near the Refuge Albert 1er is regulated by a Chamonix municipal order (2026); contact the warden.

History

The first ascent was on 20 September 1865 by Robert Fowler with Michel Balmat and Michel Ducroz, by the north side of the west ridge. Percy W. Thomas with Josef Imboden and Josef Marie Lochmatter made the second ascent on 1 August 1879 by the north side and north-west ridge, the line of today's normal route. The Forbes Arête was first climbed in summer 1899. The first ski ascent was on 26 March 1907 by Maurice Crettex, Marcel Kurz and François Frédéric Roget. The name derives from 'chardon' (thistle).
