Walter Bonatti is THE mountaineering legend, capable of meeting the great challenges of mountaineering: K2, Drus, G4, Matterhorn, to name a few. But the summits reached are not points of arrival, they are intermediate stages which then push him on a journey around the world, in search of himself. His exploration, starting from the vertical walls, then moved towards horizontal paths and was always expressed towards the interior space where our fears and our desires reside. Where the man, sitting alone in front of himself, must decide to surpass himself or to adapt. And Walter never complied with them, he wrote his own rules and followed them all his life, allowing himself no loopholes or shortcuts. He built himself as a mountaineer, as an explorer, as a photojournalist and as a writer, but always and only with the intention of being an uncompromising man with his hands, his muscles, his heart and his head.
