Down the Mighty River with Steve Backshall

Steve starts his journey at Lake Habema, the body of water where the Baliem River begins its life. Embarking on a perilous expedition, Steve encounters some of the most extreme white water rapids seen anywhere on the planet.

In this second episode, Steve and his crew kayak Baliem's lower gorge - one of the most extreme stretches of white water on the planet. With jagged rock walls looming overhead and crashing currents bearing down on the kayaks, the risk of capsizing is constant. Battling wild weather and dense jungle, Steve's explorations of the surrounding valley prove equally as challenging. Steve encounters large spiders, fierce wasp nests, and a local tribe who have little contact with the outside world.
