Cogne, the Gran Paradiso village between Valnontey and Lillaz

To reach Cogne you climb from Aosta up a side valley until it opens into the basin where the village spreads out over the meadows of Sant'Orso, at around fifteen hundred metres. It is the Aosta Valley gateway to the Gran Paradiso National Park: from the hamlets of Valnontey and Lillaz, paths lead up towards the glaciers and waterfalls. Village life once revolved around the iron mines, closed long ago.

Today Cogne lives on tourism, hiking in summer and mainly cross-country skiing in winter. Some houses are second homes or let to visitors, and the market reflects that demand. If you plan to live here all year, consider the climate (climate zone F), with long, snowy winters, and the distance to Aosta for the hospital and secondary schools. Average declared incomes are below the regional average.

There are 1,310 residents (2023), 9.8% fewer than in 2011. The average age is 49.1 against 47.0 in the region, over-65s are 27.9% and foreign residents 10.0%.

All 74 municipalities in the Aosta Valley are in seismic zone 3, and in Cogne the expected ground acceleration in the built-up area is 0.077 g. In old stone and timber houses, the checks to make are the roof, the snow load it can take and the condition of the beams.

In the high mountains, avalanches, debris flows and landslides are not the same everywhere. Starting from the address, the report identifies the land parcel and reads the official natural hazard maps for that spot.
