In a world where we rely so heavily on GPS to get from A to B, it's easy to tune out from the natural navigational clues that surround us.
Tristan, who has been a full-time natural navigator for 10 years, teaches Greg how to create an internal compass using the logic of nature, taking clues from natural forms such as plants, insects and clouds.
Deep in the Sussex woodland, Tristan shares tales of getting utterly lost and explains why navigating is a fundamental part of being human.
