Peru

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, stretching from mountains high above the clouds to the muddy, humid trails of the jungle. At the end of this epic journey they hope to find the lost city of Constitucion. To get there, they will have to endure some of the most remote and dangerous roads in South America. It's a journey that will test them both to the limit and beyond.
