Castor

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.

    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...

    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.
  • Log #22134 - by Caj E Svensson on Feb 08, 2011
    We, Eva, Caj and Anders, started out from the Val d'Ayas hut in almost alpine way just before dawn. Climbed the south slope and across the bergschrund to reach the summit ridge. Nice and narrow path...

  • Log #11919 - by Debby Richman on July 21, 2004
    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.
  • Log #11920 - by Pieter Hallewas on July 21, 2004
    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 :-)
  • Log #11921 - by Mike Rix on Nov 09, 2003
    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
  • Log #11923 - by Alberto on Aug 23, 2002
    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...
  • Log #11924 - by Mike Rooke on July 29, 2002
    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.

    I did a solo ascent of this peak as a warm up for the Matterhorn. It was a gorgeous sunny day w/ light winds. The view was stellar. The summit ridge was a very exposed (sevral thousand feet on either...

  • Log #11929 - by Ben Francis on Aug 08, 2001
    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, 2001
    we took the normal route from Kleine Matterhorn
  • Log #11931 - by Wim Roelants on Aug 05, 2001
    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...
