Presenter: Bradley Cooper & Zay Harding

Mexico's Copper Canyon is four times bigger than the Grand Canyon and is home to the mystical Tarahumara Indians. In this Treks In A Wild World, Zay Harding goes along with the effervescent Skip McWilliams, exploring unknown parts of the canyon on foot, with native Tarahumaran guides to show them the way. With ten burros, ten Tarahumaran guides and Maria the tortilla-makers, Zay encounters a land and a people that haven't changed much for hundreds of years. But Zay's biggest worry on this trip is confronting his fear of heights.

Bradley Cooper, in part two of Treks, is well ensconced in deepest Quebec, discovering the traditions of the Acadian voyageur. With a gaggle of Acadian river guides, the troupe shows Bradley the ancient art of 'poling' and learns more about a part of North America he didn't know existed.
