From Russia to Iran: Crossing Wild Frontier

Explorer Levison Wood – famous for Walking the Nile, Walking the Himalayas and Walking the Americas – takes on a new expedition in this four-part series: to cross the mighty Caucasus mountain range that lies between Russia and Iran. And as well as a new region of the world, Levison takes a new approach to exploring: making his way by any means necessary. Travelling with the locals and living as they do, Levison's epic, 2,600-mile journey takes him through five countries, crossing the wild lands on the tense frontier between Europe and Asia and visiting some of the most fascinating and diverse places on earth. Beginning in Southern Russia, Levison tracks the mountains through increasingly dangerous terrain where Islamist fighters hide out in the hills, toward Azerbaijan, Georgia, Armenia and into Iran: a highly secretive nation that's been virtually closed off to westerners for decades. Known as the 'lands in between', Levison travels through these badlands that sit at the crossroads of two continents, and form a large part of the historic and mysterious Silk Route. (Sky UK)
