Heli-skiing, Livigno

Livigno sits at 1,816 metres, in a long valley on the border with Switzerland, and it holds its winter longer than most. The official destination site counts 115 kilometres of slopes across two wide, sunny ski areas, served by more than 30 lifts. Alongside them sits a quieter offer: some 100 kilometres of backcountry terrain, where the snow is left to the weather.

Heli-skiing is how that backcountry opens up. As Skipass Livigno, the valley's lift association, describes it, the helicopter reaches the highest and most inaccessible points of the area, and the reward is a freeride descent on untracked snow in the silence above the valley. The operator Heliski Livigno, run by Heli Guides, puts a measure on it: descents of up to 1,000 vertical metres, in a mountain area framed by Cima de' Piazzi at 3,439 metres and Piz Paradisin at 3,305 metres.

What recommends the place, though, is not the flight. It is the discipline around it. In Livigno, heli-skiing is practised, in the lift association's words, under the supervision of professional UIAGM Alpine guides, with detailed briefings on the programme and on the descent before anyone flies. The destination's own account is the same: after a safety briefing, and always accompanied by a UIAGM Alpine guide. The helicopter is the easy part, and everyone involved treats it that way.

The guides have good material to work from. Through its Freeride Project, Livigno maintains an avalanche bulletin updated every morning by the Livigno Avalanche Centre, a member of the European Avalanche Warning Services association, giving detailed information on snow stability across the area. A daily snow quality bulletin sits beside it, reporting snow conditions, skiing quality and possible obstacles in three zones: alpine, forested and below the treeline. Read together, they are a ledger of the mountain, kept daily, in public.

That is the shape of a guided morning here. The bulletin comes first, while the valley is still quiet. Then the briefing, then the guide's choice of peak and route, made, as Heliski Livigno sets out, by certified guides who keep weather and snow conditions under permanent observation and choose the descents according to the conditions and to the group's ability. Only then does the helicopter lift a small group toward a slope that has earned its place on that day's list, and not the day before.

There is a generosity to the arrangement. The valley that asks this much care gives a long season in return, from December to May, with powder through mid-winter and firn, the operator notes, into spring. Below, the village goes about its duty-free business, the pistes carry the ordinary traffic of a ski day, and the high slopes stay quiet, untracked, and available only on the mountain's terms.
