Cogne Geography & Climate

Cogne sits at the point where a glacial valley flattens out, which is why there is a village here rather than just a road.

The meadow

The Prato di Sant'Orso is a kilometre-long flat floor left by a glacier, kept treeless by grazing and mowing, with the village along one edge and the mountains closing it at the far end. It is the reason Cogne looks the way it does and the reason the cross-country trails are so good.

The Gran Paradiso

The massif rises south of the village to 4,061 metres — the only peak over four thousand metres entirely inside Italy — with glaciers on its northern side feeding the valleys.

Three valleys

Valnontey, Valeille and Grauson run south and east from the village into the park, each with its own character and each ending in high pasture or ice.

Water

The Grand Eyvia drains the valley north to the Dora Baltea. The Lillaz falls drop in three stages a short walk from the village, and in winter they freeze into climbable ice.

Iron ground

The mountain above the village holds magnetite, worked from at least the medieval period, and the mine galleries run for kilometres inside it at up to 2,400 metres.

Above the trees

The treeline here sits around 2,200 metres, and above it the ground is summer pasture and then rock and ice; the hunting paths built for the king in the 1860s still cross all of it and are the trail network today.

Wildlife

Ibex, chamois, marmots, golden eagles and bearded vultures are all present and, in the case of the ibex, genuinely easy to see.

Cogne has a high alpine climate, drier and sunnier than the northern side of the Alps because the great ranges take the weather first.

Winter

Winter is long and cold, with daytime highs around 2°C and night minima well below −10°C. Snow lies from December to March on the valley floor and much longer above, and the cold is dry rather than raw.

Sun

The valley runs roughly east-west and its floor gets a great deal of winter sun, which is why the cross-country trails on the meadow work so well and why the village is a pleasant place to be in January.

Spring

Spring is late. Snow lies on the meadow into April and on the passes into July, and the flowering of the high pastures in late June and July is the best of the year.

Summer

Summer is short and cool, with highs around 22°C and nights in single figures. Afternoon thunderstorms build over the massif.

Autumn

September and October are clear, cold and the best walking, with the larches turning and the deer and ibex low on the slopes.

Precipitation

Moderate for the Alps, with a good share as snow, and the glaciers above holding what falls at height.

Snow reliability

The valley floor at 1,534 metres holds snow through the winter in most years, which is why the cross-country network here is dependable when lower Italian resorts are not; the trend is against that and everybody here knows it.

What to bring

Proper cold-weather clothing from October to May, and layers plus sun protection in every other month.
