Peru

S1, E3: Adventurer Ben Fogle and comedian Hugh Dennis drive a historic route from the Peruvian Andes to the depths of the Amazon, along roads built to conquer and exploit the natural wealth of Peru's rainforest. It's a rollercoaster ride of 2,000 foot drops and hairpin bends on one-lane dirt roads. At the end of this epic journey they hope to find the lost city of Constitucion.
