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.
