Welcome to Sports Quest, the show that takes sports to the outer limits. In this episode, we hitch a ride on an awesome tour of the world's wildest and inaccessible white water spots in the company of a team of specialist kayakers who have made a career in tackling the impossible. We head first to the vast interior of Greenland, the Indonesian island of Sumatra in South East Asia, Chile on the west side of the Andes Mountains, the Indus River in the Himalayas, and into the heart of Siberia to the Eastern Sian Mountains.
