Head to the Italian resort of Courmayeur to enjoy the Vallée Blanche without the crowds of Chamonix.
Descending close behind my guide, Beppe Villa, my head rises when I hear shouts coming from a few hundreds metres to the right. A second guide is traversing fast towards us, his skis rattling on the glass-like snow. I stop as the men talk and reach for their mobile phones. I learn only later that they are calling Alberto, their friend and another guide, who, while leading his group, has fallen down a crevasse.
I'm high on one of the world's most famous descents, the Valle Blanche. A continuous off-piste run of nearly 20km, it offers even intermediate skiers with reasonable fitness and a sense of adventure the chance to marvel at one of the Alps' most stunning regions in the shadow of Mont Blanc. Of course there are risks, posed chiefly by shifting cracks in the glacier, but they remain happily slim and the valley has become a must-do for any skier who itches to leave the piste far behind.
Typically, valley baggers arrive from Chamonix, rising to almost 3850m at the top of the cable car at Aiguille du Midi, surely the world's most dramatic lift station. A hairy walk follows before the descent starts. It can be the most dangerous part of the day if it's icy or busy, which it invariably is. I've chosen instead to join the descent from Italy and Courmayeur. The lesser-known resort lies just through the Mont Blanc tunnel from Chamonix but offers a quieter and, well, more Italian way to explore the mountains for which its cross-border neighbour is so celebrated.
I've come with friends. It takes us more than half an hour to drink in our surroundings from the top of the vast terrace at Punta Helbronner. We'd started early, ascending via a series of cable cars of increasing ricketiness to almost 3,500m. Mont Blanc dominates 360 degrees of crisp, jagged skyline, appearing so close you might consider a quick descent after lunch. Beppe, a taciturn former shopkeeper from Milan, lifts a worn finger like a sausage to point out Divine Providence, an apparently vertical triangular rock face that forms one of the toughest ascents. He was the second Italian to conquer the route.
