Ultimate Dent Blanche Guide: Wandfluegrat, Viereselsgrat & Full Logistics

The Dent Blanche (4,357 m / 14,295 ft) is one of the most distinctive mountains in the Alps — a perfect pyramid with four ridges pointing to the four cardinal directions, which gives it the appearance of a cross when viewed on a map. Guy de Maupassant, who set his 1886 short story L’Auberge in the shadow of the Dent Blanche, called it “la coquette monstrueuse” — the monstrous coquette. It is elegant and enormous, alluring and lethal. The mountain dominates the head of the Val d’Hérens and the Val d’Anniviers, and stands at the linguistic boundary between French-speaking and German-speaking Switzerland.

Alongside the Weisshorn, Zinalrothorn, Obergabelhorn, and Bishorn, the Dent Blanche forms the “Imperial Crown of Zinal” — the semicircle of great peaks that frame the Val d’Anniviers above the village of Zinal, one of the grandest amphitheatres of high peaks in the entire Alps. Among these, the Dent Blanche stands highest and most iconic, its four-sided pyramid rising almost entirely from rock with almost no permanent ice on its flanks — despite its name, White Tooth. The name is a cartographic error; the Dent Blanche holds almost no snow.

Two features define the Dent Blanche experience. The Cabane de la Dent Blanche (Cabane Rossier) at 3,507 m is the highest-altitude SAC refuge in Switzerland, reached by a 1,700-metre approach from Ferpècle that is an alpine undertaking in its own right. And the South Ridge (Wandfluegrat, AD) is described by expert alpinists as “one of the Alps’ true masterpieces” — solid gneiss, aesthetic ridge climbing with the Matterhorn directly behind the route as a backdrop, and a serious enough challenge that it is never crowded.

History & First Ascent

Kennedy, Croz & the Four Asses — A Mountain of Stories

Thomas Stuart Kennedy — A Matterhorn Attempt, Then the Dent Blanche, July 1862

Thomas Stuart Kennedy was one of the most determined British alpinists of the Golden Age — a man of exceptional persistence. In January 1862, he had made the extraordinary attempt to climb the Matterhorn in winter with guide Peter Taugwalder. Edward Whymper sneered at the idea; the mountain, predictably, refused them. Then in July 1862, Kennedy attempted the Dent Blanche with the Taugwalders again. High on the mountain, Taugwalder senior slipped and was badly frightened. Kennedy writes: “I heard [Taugwalder senior] clattering down, and was surprised to see the weatherbeaten old fellow with a face as white as that of a frightened girl. He seized eagerly upon some spirits of wine we chanced to have… his nerve being entirely destroyed by the fright, I fixed the rope round my own waist, and led the way upwards.” The Taugwalders refused to continue, and Kennedy was obliged to descend.

He returned a week later. On July 18, 1862, Kennedy reached the summit of the Dent Blanche with William Wigram and guides Jean-Baptiste Croz and Johann Kronig, via the South Ridge. It was the first ascent of one of the highest and most beautiful mountains in the Alps, in adverse weather conditions. The same year was the apex of the Golden Age: 1862 alone saw the first ascents of the Dent Blanche, the Bietschhorn, and others. The Matterhorn, which had repulsed Kennedy in January, would fall three years later.

Jean-Baptiste Croz — The Guide Who Died on the Matterhorn

The guide Jean-Baptiste Croz who stood on the Dent Blanche summit with Kennedy in 1862 was the younger brother of Michel Croz — the great Chamonix guide. But Jean-Baptiste was also the same man who, three years later on July 14, 1865, was among the four people who died in the catastrophe of the Matterhorn’s first ascent. Croz, along with Charles Hudson, Douglas Hadow, and Lord Francis Douglas, fell to his death on the descent. He had guided brilliantly on the ascent — leading the final steep pitches to the summit — before the tragic descent fall. The Dent Blanche first ascent with Kennedy in 1862 stands as one of Croz’s greatest achievements, three years before his death made him famous for the saddest of reasons.

The Viereselsgrat — “We Are Four Asses,” August 11, 1882

The East Ridge (now called Viereselsgrat or Arête des Quatre Ânes) was first climbed on August 11, 1882 by John Stafford Anderson and G.P. Baker with guides Alois Pollinger and Ulrich Almer, starting from the Mountet Hut. They took 12 hours on a dangerous, difficult ridge overlooking the north face. Upon finally reaching the summit, guide Ulrich Almer made the comment that has defined the ridge ever since: “Wir sind vier Esel” — “We are four asses.” Whether Almer meant that they had been foolish to attempt such a route, or simply that it had been harder than expected and they were proud idiots to have done it, the remark stuck. The ridge has been known as the Viereselsgrat (Four Asses Ridge) or Arête des Quatre Ânes ever since — one of the most delightful route names in the Alps.

O.G. Jones — The North Ridge Tragedy, 1899

On August 28, 1899, Owen Glynne Jones — one of the finest British rock climbers of the Victorian era, whose name adorned routes on the British crags and who was blazing through the Alps at extraordinary speed — headed for the Dent Blanche north ridge with F.W. Hill and guides Furrer, Zurbriggen, and Vuignier. The party fell. Jones, Furrer, and Vuignier were killed; only Hill survived. Hill, alone and in shock, continued to the summit. A storm then pinned him there, forcing him to bivouac in the elements above 4,300 m. He could not report what had happened until he descended to Zermatt — two days after the accident. O.G. Jones was 32 years old. He had been on the cusp of becoming one of the defining figures of British mountaineering. His death, like Bennen’s and Croz’s, underlines the fundamental difference between Victorian alpinism and modern Alpine climbing.

Dorothy Pilley Richards — The NNW Ridge, July 20, 1928

The north-northwest ridge — described at the time as “one of the last great problems of the Pennine Alps” — was first climbed on July 20, 1928 by Dorothy Pilley Richards with guides Joseph Georges and Antoine Georges. Dorothy Pilley Richards (1894–1986) was one of the outstanding British climbers of the inter-war period — a woman who pursued serious technical climbing at a level that placed her among the leading alpinists of any gender. She later wrote up the ascent in her mountaineering memoir Climbing Days (1935), one of the most celebrated books in British mountaineering literature. The first ascent of the NNW ridge was her finest alpine achievement: a bold first on a route that had resisted all previous attempts.

Geology & Name

The African Mountain — And the Name That Was a Mistake

Why “White Tooth” Has Almost No Ice

The Dent Blanche’s name means White Tooth in French — yet the mountain is almost entirely ice-free. Even in the heart of winter, it is more grey rock than white snow. The nearby Dent d’Hérens has a heavily glaciated north face; the Dent Blanche, despite its “white” name, does not. On the Woerl Atlas of 1842, the Dent Blanche was actually called “Dent Noire” — Black Tooth — which was more accurate. The confusion arose because early cartographers worked from distant observation, often confusing the Dent Blanche with the heavily-iced Dent d’Hérens behind it. The name swap stuck, enshrined by successive maps and finally confirmed on the Dufour Map of 1862 — the same year as the first ascent. The Dent Blanche received the “White” name despite holding almost no permanent ice; the Dent d’Hérens bears the “Hérens” name despite actually lying outside the Val d’Hérens, which the Dent Blanche overlooks. Even the local inhabitants in the mid-19th century called the Dent d’Hérens “Dent Blanche” — the confusion ran in every direction.

The Dent Blanche Nappe — African Rock That Also Built the Matterhorn

The Dent Blanche is geologically extraordinary: it is built of rocks from the Dent Blanche nappe — an ancient fragment of the African (Apulian) plate that was thrust over the European plate during the Alpine orogeny. These are some of the oldest rocks in the Alps, carried vast distances by tectonic forces before ending up as a mountain in Switzerland. The same African rocks form the summit of the Matterhorn — the Matterhorn above 3,400 m is composed of Dent Blanche nappe gneiss, not European rock. This means the geological substance of the Dent Blanche is quite literally inside the Matterhorn. The Weisshorn, Zinalrothorn, and several other nearby peaks are also built of Dent Blanche nappe material. Standing on the Dent Blanche summit, you stand on Africa.

Getting There

The Val d’Hérens — A French-Speaking Dead-End Valley

The Dent Blanche is accessed from the Val d’Hérens — a scenic, French-speaking side valley in Canton Valais that ends at the village of Ferpècle. This is the start of the hut approach. The valley is described by multiple sources as a “tucked-away side valley” with preserved farmhouses, ancient villages, and traditional mountain architecture. It is also the emergency exit for parties descending from the winter Haute Route ski traverse when weather closes in — many ski tourers descend to Ferpècle or Arolla having never climbed the Dent Blanche. The drive out promises a return visit that the mountain richly deserves.

Complete Route Listing

All Routes on the Dent Blanche — Four Ridges, Four Characters

The Dent Blanche’s four ridges correspond precisely to the four cardinal directions, each with a distinct character and history. SummitPost notes: “So this is not a climb for everybody” — even the easiest route (South Ridge, AD) is demanding by alpine standards. The north face is one of the most serious north faces in the Alps.

Difficulty & Safety Notes

AD on excellent rock — but not for everyone

The South Ridge is AD — genuinely one of the finest moderate routes on any Alpine 4,000m peak. The rock is excellent, the route is logical, the bolts and ring bolts are placed where needed. But SummitPost’s summary verdict applies: “So this is not a climb for everybody.”

• The 1,700 m approach is a day’s work: The approach from Ferpècle to the Cabane Rossier involves 1,600–1,700 m of gain in 5–6 hours over demanding terrain. Parties who are tired from the approach will be dangerously fatigued on summit day. Be honest about fitness going in.
• Snow changes everything: In dry conditions, the South Ridge is a classic rock climb on excellent gneiss. After snowfall, it becomes a much more serious mixed and ice route. The character changes dramatically depending on conditions. Check recent trip reports and the Cabane warden’s assessment before committing to the summit.
• Rockfall in the Grand Gendarme gully: The gully to the left of the Grand Gendarme funnels parties through the same terrain. If parties are above you in this gully, dislodged rock falls directly onto those below. Give adequate vertical distance and time parties above carefully. Helmet mandatory throughout.
• The approach glacier: The hut sits above a glacier that is rapidly retreating and changing. The approach route from Ferpècle passes the Glacier de Ferpècle; conditions change annually. Crevasses, moraine, and ice sections may be encountered — treat the approach with appropriate glacier awareness even if it looks straightforward.
• Guide strongly recommended: The Dent Blanche is consistently described as a mountain where a guide adds enormous value — both for current route knowledge (the Wandfluegrat changes with conditions) and for managing the crux sections safely. ALPSinsight’s experienced assessment: “This is one of the Alps’ true masterpieces.” Respect it accordingly.
