The Matterhorn is one of the most beautiful mountains in the world, but also difficult to climb and thus one of the most coveted ascents in the Alps. Hervé Barmasse knows this well, and acting as an exceptional mountain guide and storyteller, accompanies us on the standard Italian route, the Lion Ridge, considered the star route in the Alps. In a roped party with Hervé, we retrace its conquest, find out about the leading figures involved and take on the toughest stretches to the 4478 metre high summit.
