Mountaineering. The art of getting from the bottom of a mountain to the top of a mountain. Sometimes this involves hiking, sometimes this involves climbing, and sometimes this involves sleeping in a tent that's dangling from a cliff face hundreds of feet above the ground. Needless to say, it's not the ideal activity for someone with a fear of heights.

To celebrate the new Berghaus Extrem range, and those daring adventurers who quite literally take mountaineering to new heights, we've compiled this collection of vertigo-inducing imagery of people getting high in the great outdoors. A word of warning: prolonged staring at these photographs might make you feel a bit dizzy.
