Mysteries of the Mekong

The Yunnan Province in China marks the first leg in the 2,700-mile journey of the Mekong River. Fed by countless tributaries and glacial meltwater, it traverses the land it helped shape, giving sustenance to the region's exotic, and often endangered, wildlife. Join us as we map the path of this mightiest of rivers.

As the Mekong River snakes its way through Thailand, touching the borders of Burma and Laos, it hits a mountainous region of dense forest: the Golden Triangle. Home to 10,000 exotic plant species, it also serves up a rich mix of wildlife, from rare langurs to Asian elephants and majestic cranes.
