Nat Geo Adventure’s new series First Ascent journeys alongside the world’s best climbers as they attempt to conquer the most forbidding peaks.  BASE jumping, free soloing and mountain climbing in its many forms are not for the faint-hearted.  In this tight-knit sporting community, experienced mountaineers demonstrate an intense passion for climbing – and for supporting each other’s endeavours – as they push themselves to their absolute limits.  With cameramen following every step of the way, the series captures the unyielding determination, heart-stopping moments, emotional rollercoasters and spectacular visuals that can only be seen from hundreds of metres above a sheer cliff face.
