Just when you think it can’t get any hotter, Les Stroud finds out it can. In this episode, Les dips his toes in the scorching red sands of the Kalahari Desert — one of the most extreme climates on Earth.

The phrase “It’s a jungle out there” takes on a whole new meaning when Les Stroud pays a visit to one of the densest, deepest parts of the Amazon jungle. For seven days, Les “Survivorman” Stroud will test his mettle, his will and his ingenuity — everything he’s got — to survive in one of the most dangerous places on Earth.

For this episode, Les Stroud goes to the dogs — literally. Our intrepid Survivorman relies on seven Inuit sled dogs (Labrador huskies) to pull his dog sled into the wilds of Labrador. He embarks on this dangerous journey at the tail end of winter, when the weather is the most unpredictable.

The plains of South Africa conjure up images of beauty — and danger. In this episode, Les Stroud lands here for an arid adventure that would make even the most seasoned safari traveler sweat. And not just because of the heat.

This time Survivorman decides to demonstrate survival by sea kayak in an ocean bay called Taroka Arm (literally "black bear") for good reason. At this time of year, the salmon are active and are one of the black bear's favorite foods. Black bear and grizzlies that live in this area are among the largest in the world and gorge themselves on the silver salmon during this period.

Les explains his preparation for each locale in this behind the scenes look at the episodes of season 2.
