Remote and wild, the Yukon is a river of extremes. In summer, a restless giant and in winter, it becomes a river of ice. Home to bears, moose and salmon, the Yukon’s riches have sustained North American people for centuries.

Featuring breathtaking photography, the second season of this landmark series explores Africa’s wildest river, the Zambezi; Europe’s Danube River, which travels through more countries than any other river; and North America’s great frozen river, the Yukon. Journey from source to mouth and travel through awe-inspiring landscapes to discover the spectacular wildlife and fascinating people that thrive along three of Earth’s greatest rivers.
