Watch on 123Movies. What does it take to know a mountain? Tired of all the stories focused on racing to the summit, Hannah Westhenry fell into the pages of her beloved book The Living Mountain, by Scottish writer and explorer Nan Shepherd. Inspired by Nan’s work, Hannah brings together a diverse group of women to follow in Nan's footsteps, adventuring into the UK's largest and wildest mountain range to tell a different story. To Know A Mountain interweaves visuals of the Cairngorms – from its grand landscapes to its smallest details – into an anti-summit story, promoting inclusion in the outdoors, and representing a diversity of ways of being in the mountains not often told in adventure films.
