Explorer Levison Wood takes on a new challenge: to walk the length of the world’s highest mountain range, from Afghanistan to Bhutan. Taking the same intimate and authentic approach that made his previous series, Walking the Nile, a hit, Levison treks 1700 gruelling miles over four months, teaming up with local guides, meeting monks, soldiers and nomadic tribes and passing through some of the most remote, beautiful and perilous regions on Earth: places few outsiders ever get to see.
