Video profile of Catalan alpinist Silvia Vidal, one of the world's foremost big wall climbers. Solitary first ascents of new routes. But not any old rock climbs: routes which are a 1000 metres high and more, in severe surroundings, remote, past severe difficulties up to A4. In short, almost the maximum of big wall climbing. Ascents that are almost always carried out alone by the small and tough Catalan alpinist Silvia Vidal. Certainly a true player in the mountaineering world, well worth finding out more about.
