Castore 4226 m - Castor in German - is one of the classic mountains of the Monte Rosa massif in the Pennine Alps. It is located on the border between Valle d'Aosta (Italy) and Valais (Switzerland), along the main alpine watershed running from Breithorn to Punta Dufour. More in detail it is located between the Polluce, from which it is separated from the Passo di Verra 3845 m, and the Western Lyskamm, from which it is separated from the Felikjoch 4061 m. Together with its neighbour Polluce - or Pollux - it forms the "Gemelli" or "Zwillinge" ( "the twins"), as the locals call them. This particular shape appears especially when "the twins" are observed from the Swiss side. Their names derive from the Greek mythology. Higher than Polluce, Castore is one of the 4000s most visited in the Alps and one of the favorite destinations for climbers: in good weather it is not difficult to count dozens of people on the top. Check here the complete list of the 82 alpine Fourthousanders and the 46 minor summits: Club4000.
Particularly inviting because very aesthetic and not too difficult is the access from the Refuge Quintino Sella, where it starts the Normal Route on the South-East ridge. Castore does not present a climb with great technical difficulties along this route: the small ridges to overcome to reach the summit are very funny, though quite airy.
To this aesthetic snowy South-East ridge starting from the Felikjoch is opposed a steep ice slope facing North-West where it runs another frequently climbed route with access from the Colle del Breithorn. The Colle del Breithorn can be quickly approached both from the Testa Grigia, point of arrival of the Breuil-Cervinia cable car (Italy), and from the point of arrival of the Klein Matterhorn cable car. Castore can be climbed directly by traversing to South-East across the Verra glacier for about 1,30 to 2 hours to get the base of the mountain, then about a 45 minute push to the top.
The NW route can be approached also from the Val d'Ayas across the Vallone di Verra with the huts Mezzalama and Guide della Val d'Ayas.
Another classic route starts from the Monte Rosa hut up and over the Zwillingsgletscher to the border ridge and to the summit. This is a long hump over 6-8 hours one way. Because of crevasses it is not recommend as a solo route.
Starting from the Italian side the routes to summit Castore are mainly two, the SE ridge and the NW slope. The SE ridge is the easiest route, so it's considered the true Normal route and starts from the Rifugio Quintino Sella 3585 m. The approach to the refuge is from Stafal 1825, in the upper Valle Gressoney.
The NW slope has two different approachs:
- via the Rifugio Guide del Cervino, Testa Grigia (approach from Breuil-Cervinia, Valtournanche)
- via the Rifugio Guide d'Ayas (approach from Champoluc, Val d'Ayas
So there are three different Aosta valleys with three different road approaches, depending from the itinerary you have chosen
Getting to Stafal (Valle di Gressoney)
The village of Stafal m. 1825, located in the high part of Valle di Gressoney, Aosta Valley can be reached from the A5 Motorway, exiting Pont St Martin, then following the Valle di Gressoney until the end of the road.
From Stafal m. 1825 to the Rifugio Quintino Sella m 3585
From the parking area a cable car leads 300 meters further up, where a chair lift by a long run leads up to Passo di Bettaforca m 2720. Here take the obvious path n. 9 to the Quintino Sella shelter, rising on the crest and getting quickly to the Bettolina Pass m. 2905. From here carry on the wide crest to the junction with the path coming from Pian di Verra. Follow the yellow marks, climb up some easy rocks, then follow the final airy ridge, equipped with fixed ropes, leading to the terrace on which is located the Rifugio Quintino Sella m. 3585.
The quick approach to the NW slope starts from Rifugio Guide del Cervino m. 3480, located near the upper station of Testa Grigia cable-car, starting from Breuil-Cervinia, while the longest approach is from Rifugio Guide d'Ayas.
Getting to Breuil-Cervinia
Breuil – Cervinia is a major mountain resort, located at the end of the Valtournanche, Aosta Valley. Can be reached from the A5 Motorway, exiting Châtillon/Saint-Vincent, then following the Valtournanche. Public transportation is easy to arrange.
Getting to Champoluc
Another route starts from Rifugio Guide d'Ayas across Rifugio Mezzalama. The route to reach this huts starts from St. Jacques, a hamlet of Champoluc in Valle d'Ayas, Aosta Valley.The village of Champoluc can be reached from the A5 Motorway, exiting Pont St Martin, then following the Valle di Gressoney until the end of the road.
From the Klein Matterhorn Cable Car station.
Starting from Zermatt, on the Swiss side, the Castore can be climbed across the NW flank via the Klein Matterhorn Cable Car station. It can be reached by taking the cable car all the way from Zermatt or one can hike up to it from the Gandegg hut in about a 1/2 to 1 hour walk. One could also stay at the Hotel Schwarzsee which is furter away than Gandegg at about 1-1/2 hours hike.
From the Monte Rosa Hut
The longest way to summit Castore is from the Monte Rosa Hut. Approaches:
- from the station Rotenboden (Gornergrat cable car) over the Gornerglacier in 2 - 2,5 h, 200 m up and down. The route on the glacier is partially marked by poles. From the station Rotenboden, you choose the way with S-direction to the ridge saddle in the E of the Riffelhorn (signs). After about 100 meters, the route goes up over the Gornerglacier to the E and slightly down to the S-flank of the Gorner-ridge. You reach the Grenzglaicer and traverse it to the S till you reach the E-side of the Grenzglacier. You climb up on the glacier below the hut. You reach the hut via the moraine with short zigzag (100hm).
- from the station Stockhorn. You pass the Stockhorn in 30 min. to the E to the Stockhornpass and traverse the Gornerglacier at the foot of the Punta Nordend (NW). Then you go at the left side down and along the Monte-Rosa-Glacierbreak and the rocks. You reach the edge on about 3120 m (pole). You go up slightly on the S-side and traverse the middle tongue of the Monte-Rosa-glacier to the Unteren Plattje and the hut (2-3h)

First ascent: William Mathews and F.W. Jacomb with the guides J.B. Croz and Michel Croz 23- august 1861
A fine route - entirely glacial - without particular technical difficulty, but the ridge is airy and sharp and it should not be underestimated
- Castore WNW Flank Click this link on SP providing the full report of this route
Difficulty: Alpine PD+
It's the second route usually climbed to reach the summit, a little more demanding than the previous route. The final ascent is made from the Zwillingsjoch, a 3848 m high pass on the Western side of Castore. As previously told the Zwillingsjoch may be approached from four different starting points:
- from the Rifugio Guide del Cervino on Testa Grigia cable-car upper station (Italy, Cervinia)
- from the Klein Matterhorn station 3883 m on the Swiss side of the border with Italy (Switzerland, Zermatt)
- from the Rifugio Guide d'Ayas (Italy) - from the Monterosa Hut (Switzerland) - it's the longest approach

You cross the glacier and pass on the Grenzgletscher, then you head to the Untere Plattje morain and climb it to get the refuge. 2,30-3 h. Winter: as Monte Rosa Hütte can also be reached from Stockhorn, where you arrive by the train to Gornergrat and then by the cableway to Hohalligrat and then by the same Stockhorn. And you can also cross the ridge to the Gornergrat. Once at the Stockhorn pass, continue towards Plattje Unteren, reaching the refuge in about three hours. An additional possibility is to start from the Furi locality through the Gorner glacier: an itinerary of about 9 kilometers not marked and must be built by trained people, preferably on a rope. The difference in height is 940 meters, the time is 4 hours.
The particular names Castor and Pollux, or Gemini, come from the Greek mythology and refersto the two twin deities called "Diòscuri", sons of Zeus. They were worshiped in the ancient Greece as protectors of sailors. The reason of the name derives from the particular form of twin peaks that Castore has together with the Pollux. The first ascent of Castore was performed in 1861, August 23 by the two British alpinists F.W. Jacomb and W. Mathews with J.B. and M. Croz. Castore has become famous also in reason of the transit of the "Ottorino Mezzalama" ski-mountaineering contest, a big course with ski that starts from Teodulo (Cervinia) and ends in Gressoney, after having passed the Lyskamm Nose.
Mountaineering. from June to September (crowded in July and August)
Ski-mountaineering: Good at all times except when there are heavy snow conditions can cause local avalanches.
