“The mountain is a superb playground, it is up to us to invent the story that goes with it”

Born in Marseille, Martin Kern is a jack of all trades: from paragliding to mountaineering, ski touring, cycling and ultra-tail. The Calanques were his first natural playground, then after a few years abroad, he settled in the Alps where he now lives.
