Extreme rock climber Adam Ondra taking on the Hanshelleren cave in Norway

Silence follows professional rock climber Adam Ondra, currently one of the best climbers in the world, conquering the Hanshelleren cave in Norway – also called “Silence”.

The Hanshelleren cave is one of the absolute hardest cliff-faces in the world to climb, even receiving a new grade of 9c (5.15d – a grade reserved for the very few elite).

Like a giant eye socket set in a hillside, the Hanshelleren cave in Flatanger – claimed by some as the world’s greatest climbing cliff – has become a summer mecca for the world’s best climbers who come to dodge the Scandinavian showers and pit themselves against its vast overhangs.

Now, after over 40 days of efforts spread across two years and seven visits to Norway, Ondra has completed what is being claimed as the world’s hardest single rope-length climb, both in terms of physical effort and technical difficulty.

The climb – 45 metres long and forging its improbable way through the cave’s huge grey overlapping roofs – marks the latest achievement by Ondra, who has dominated rock climbing in recent years in the same way Usain Bolt dominated sprinting, consistently setting new levels of difficulty that others have struggled to follow.
