Intrepid Nick Knowles sets off on another ambitious adventure for Channel 5, this time to South America.

From the self-styled ‘end of the world' in Chile, Nick treks to the astonishing Torres del Paine National Park, considered by some to be the eighth wonder of the world. From the lake district, he visits a Chilean archipelago in the Pacific and its largest island Chiloe, home of witches, and finally traverses the Andes to end his South American odyssey in Argentina.
