The Devil's Climb

Alex Honnold and Tommy Caldwell are two of the greatest rock climbers of all time — and best friends.

Together, they set off on an epic adventure, cycling 2,500 miles en route to a daring climb of the Devils Thumb, a legendary 9,000-foot Alaskan peak surrounded by old-growth rainforest.

Tommy is recovering from a career-threatening injury, making the expedition’s success uncertain.
