Champorcher, the valley above Bard and the Mont Avic park

Champorcher lies at the head of the valley of the same name, which climbs south from the Dora valley floor, near Hône and Bard, to over 1,400 metres. The village is spread across hamlets of stone and timber houses, among meadows, larches and the peaks bordering the Mont Avic nature park. In winter there is a small ski area, in summer walkers and families.

For a buyer this is real mountain living: climate zone F, snow for months, a valley road with many hairpin bends. Services, secondary schools and the railway station are down at Hône-Bard and Pont-Saint-Martin, while Aosta is further away. Many houses are second homes and tourism keeps bars, restaurants and accommodation going: 18.97 places to eat per 1,000 residents, against 9.39 across the Aosta Valley.

Istat, the national statistics office, recorded 369 residents in 2023, 7.3% fewer than in 2011. The estimated average age is 52.1, against 47.0 for the Aosta Valley, and over-65s make up 30.6%. Declared incomes are below the regional average.

For earthquakes the whole region is in one zone: Champorcher is in seismic zone 3 on the Civil Protection Department's scale, like all 74 municipalities in the Aosta Valley, with expected ground acceleration of about 0.057 g. Snow, avalanches and slopes weigh more here: read the official maps for the address, and before buying look at the roof, insulation and winter access.

Revenue Agency (Agenzia delle Entrate) cadastral maps are published and the report finds the land parcel from the address.
