13. Kimberly, Australia

In the Kimberley region of Australia, an area with a mixture of huge scrub deserts, dry riverbeds and red sandstone cliffs full of deep gorges, Grylls faces extreme heat, poisonous snakes and the ever present danger of dehydration. Survival tips include how to forage for food (bush tucker), build a shelter and how to prevent sunstroke. He explains why he believes drinking ones own urine can prevent death from dehydration. During his journey, Grylls observes saltwater crocodiles and endures a lightning storm.
