Simon Reeve journeys deep into Canada's vast and empty Yukon Territory – one of North America's most iconic and remote landscapes. Covering an area almost the size of Spain but home to fewer than 50,000 people, the Yukon is a land of immense forests, glaciers, rivers and wildlife. In wealthy, modern Canada, Simon wants to find out how the people and the wildlife of this immense wilderness are faring - all while searching for an apex predator, the grizzly bear.
