A long glacier traverse from the Klein Matterhorn lift past the Breithorn and the Schwarztor to the foot of the south-west ridge, then easy broken rock (II), a chain-equipped slab (III) to a Madonna statue, and a short snow crest to the 4,089 m summit. About 3 hours up; queues at the chains are common.

About <1% of this line is approximate (no mapped trail; drawn from the terrain). Check it against a map before relying on it.

Why? 3 check notes
  • ascent 523 m is 2.0× the net gain 264 m: the line probably detours down and back up (not a traverse)
  • unresolved waypoints: Madonna statue
  • waypoints not on the route line: Breithornpass (222 m off the trail), Schwarztor (226 m off the trail)

From the Klein Matterhorn top station (about 3,820 m) walk onto the Breithorn plateau, go east past the Breithornpass and leave the Breithorn track. Traverse the upper Verra Glacier (Grande Ghiacciaio di Verra) eastwards below the Central and East Breithorn and Roccia Nera, passing below the Rossi-Volante bivouac and the Schwarztor (about 3,730 m), then climb east to the foot of the south-west ridge (point 3,793 m). The glacier is heavily crevassed and gets the morning sun early. From the Rifugio Guide della Val d'Ayas (3,420 m) on the Italian side, follow the Verra Glacier north-east towards the Zwillingsjoch and turn left up a steepish north-facing slope at about 3,750 m to the same point. The ridge starts in scree or snow on its west side. Follow the polished line on or just south of the crest over easy blocks (II), turning three small towers on the right and passing left of a red tower, to slabs equipped with chains and bolted belays (III/III+). These lead to a small rocky promontory with a statue of the Madonna, which many people mistake for the top. A snow ridge of about 100 m vertical leads to the summit. Camptocamp gives about 3 hours from Klein Matterhorn; the SAC gives 2½–3 hours and 670 m from the Guide d'Ayas hut. Descend the same way, abseiling at the chains if busy, or go down the south-east ridge (a few moves of III on slabs, or a path to its right) to the Zwillingsjoch and back across the glacier, or on to Castor. When the ridge is snow-free and dry the rock is loose and polished; when plastered it is noticeably harder. The return to the lift involves about 250 m of re-ascent to the Breithorn plateau in afternoon snow.

Overview

Pollux (4,089 m) is the lower of the 'twins' with Castor on the Swiss–Italian border east of the Breithorn. Its normal route crosses a long, crevassed glacier from the Klein Matterhorn lift, then climbs a short rock ridge with chains to a Madonna statue and a snow crest to the summit.

Pollux and its higher neighbour Castor take their names from the twins of Greek myth and rise from the Monte Rosa glaciers above Zermatt and the Val d'Ayas. Pollux is a compact rock peak with a snow cap. It stands east of the Schwarztor and the Breithorn's Roccia Nera and west of the Zwillingsjoch (Colle di Verra), which separates it from Castor. The north face drops to the Schwärze Glacier and the Gorner basin; the south side looks over the Verra Glacier into Italy.

The normal route by the south-west ridge is a popular short alpine climb: an hour or so of easy scrambling and a chain-equipped slab of about III, between a long glacier approach and a short snow ridge. Thanks to the Klein Matterhorn lift it can be done in a day from Zermatt, which makes the chains a bottleneck on fine summer days. Many parties combine it with Castor or with a hut-to-hut traverse of the Monte Rosa 4,000ers, sleeping at the Guide d'Ayas hut.

Conditions vary a lot. With good snow cover the glacier is straightforward and the ridge is short; in dry late summers the Verra Glacier is a maze of open crevasses, and the ridge becomes loose, polished rock where crampons scrape and parties above dislodge stones.

Climbing Notes

Suitable for climbers with roped glacier travel and crevasse-rescue experience who can move confidently on exposed grade II–III rock in crampons. Beginners should go with a guide; Zermatt and Ayas guides run Pollux and Castor regularly, often as a two-day trip via the Guide d'Ayas hut.

Acclimatise first (for example with Breithorn West or a night at the Guide d'Ayas hut). From Zermatt, take the first lift to Klein Matterhorn; allow about 3 hours to the summit and a similar time back, including the reascent to the Breithorn plateau in soft afternoon snow, and check the last cable-car descent. On busy days start early or climb the south-side variant to avoid the queue at the chains. In dry conditions, wear a helmet and keep parties close together on the ridge.

History

Jules Jacot of Geneva with the guides Josef-Marie Perren and Peter Taugwalder (the father, who was on the Matterhorn the following year) made the first ascent on 1 August 1864.
