Starting from the Klein Matterhorn, the route on skis heads across the Breithorn plateau and along the Breithorn before heading to the 4,000-metre twins Castor and Pollux. This takes you to the Schwarztor, the gap between Roccia Nera (eastern end of the Breithorn) and Pollux. Ski tourers then enjoy a long, powder snow descent through a labyrinth of incredible crevasses and seracs down to the Gorner Glacier and on to Zermatt.

  • Up close to the 4,000ers around Zermatt
  • Spend the whole day on the glacier
  • Challenging navigation on the descent
