Scotland

Grylls shows how to navigate the Cairngorms region in extreme weather using ice formations and moss growth, and how to test snow slopes for avalanche potential. He uses moss to purify water and skins a red deer for shelter. For food, he traps a rabbit and cooks it to demonstrate how to prepare it. Grylls also crosses deep marshes and uses fallen trees to cross ravines.
