Alex Honnold in the Swiss Alps

Free Solo rock-climber Alex Honnold joins Bear Grylls for a breathtaking adventure through the Swiss Alps! Alex is no stranger to dizzying heights, but he’s not used to falling from them, so Bear kicks off the journey with a skydive into the jagged mountains. From there, it’s a six-mile trek through craggy valleys and sheer cliffs where Bear teaches Alex how to survive in the wild, but the tables turn when Alex takes Bear on a hair-raising climb.
