Featured photo of Castor

Castor is one of the easiest 4000 meter peaks in the Alps. Together with Pollux, it forms the "Zwillinge", which is German for twins. In high season it can be really crowded on the peak, for many climbs (often with guide), are made from the Klein-Matterhorn cablecar-station at 3883m. The mountain is much more impressive from the Italian side then from the Swiss, and heavily glaciated on all sides. The view is magnificent; To the east in the distance the mighty Mont Blanc massif; closer Dent d'Herence, and Matterhorn. Mostly the ascent is made over the Passo di verra (Zwillingsjoch), at 3845m.

    Great upward trek. Really nice day coupled with Pollux. Traveled from D'Ayas to Sella Hut, by going over Castor. Very windy on ridge during this ascent, so weather conditions matter.

    Beautiful peak for a first 4000+ altitude experience. Only the last part on the thin iceridge requires some concentration. Descent to the Gnifetti hutte in wonderful powder :-)

    An easy peak with a nice view. We had a perfect day, and very good snow conditions. The only difficulty were a few meters on the final ridge, a bit exposed.

    Nice peak! I was there last summer with a beautifol day, coming from the hut Guide d`Ayas, after climbing the Pollux. Ciao

    Quick and easy ascent from west ridge, after a scary descent from Pollux by east ridge: unstable rock/stones and too soft snow. If you want to cross Pollux, is better to climb from east ridge to the...

    Walked in from the Kleine Matterhorn ski slopes. Navigation was easy due to the number of parties in front of us. A super steep climb up on to a short narrow summit ridge. Great views.

    An easy walk, with a steep slope, then a great final short ridge to the summit. Just watch out for the Bergmeisters - they have egos as large as the mountains!
  • Log #11930 - by isabel Breyer on Aug 06, 20013.00 stars
    we took the normal route from Kleine Matterhorn
  • Log #11931 - by Wim Roelants on Aug 05, 20013.00 stars
    From Quintino Sella Hut to Klein Matterhorn (the reverse way). Easy from hut to summit. Alone on the summit. The Klein Matterhorn crowd didn't arrive yet.

    My second 4000 mt. Everything was great but visibility: no more than 50 meters.

    We had to turn around 150 meters before the peak because I had problems with my crampoons and the leg to my german friend broke down. That means I have to return next summer and pay a fortune to...

    Beautiful climb. Not that difficult if one is comfortable in crampons, using an ice axe and walking on a narrow ridge. Long slog to and from the Klein Matterhorn cable car.

    We woke up in a strong and freezing wind and decided to wait for better weather, as it was forecasted. Those who left the refuge Quintino Sella, on the Italian side, despite the wind, came back a...
