Bear Grylls is a seasoned adventurer who served with the Special Air Service, a special forces unit of the British army, where he was trained as a survival expert. His experiences include climbing Mount Everest, crossing the freezing North Atlantic Ocean in a small, open boat and climbing a Himalayan peak described by Sir Edmund Hillary as unclimbable . He has been places and done things that would defeat most normal people. But now, he is up against something completely different. In each episode of Man vs. Wild , Bear strands himself in popular wilderness destinations where tourists often find themselves lost or in danger. As he finds his way back to civilization, he demonstrates local survival techniques, including escaping quicksand in the Moab Desert, navigating dangerous jungle rivers in Costa Rica, crossing ravines in the Alps and surviving sharks off Hawaii.
