Glide with the river as it flows past red pandas and remote human settlements on the Tsangpo Gorge to emerge into India’s temperate forests. Then discover lush Assam, with its tea plantations, iconic one-horned rhinos, and the last wild pygmy hogs.

3. From the Plains to the Ocean
Aired 15 October 2020 • 52 min
