Challand-Saint-Victor, the lower Ayas valley along the Evançon
Driving up from Verrès towards Champoluc, the first municipality you cross is Challand-Saint-Victor: it covers the lower Ayas valley, with hamlets scattered on both sides of the Evançon stream and the town hall at around 750 metres. The main Dora valley and the Aosta Valley motorway are close by, which is what makes the village workable all year round for people who commute further down.
Homes are mostly hamlet buildings in stone and timber, with stone-slab roofs in the oldest clusters, alongside more recent houses. Some are second homes. This is climate zone F, the coldest category, so insulation, windows and heating weigh heavily on yearly costs, and it is worth finding out how snow is cleared on the access road.
In 2023 there were 546 residents, down 10.6% on 2011. The average age is 46.2, slightly below the regional 47.0, and over-65s make up 23.8%. Foreign residents account for 6.8%. Declared incomes are below the regional average.
In the Aosta Valley the seismic classification is the same everywhere: all 74 municipalities in the region are in zone 3, and the expected ground acceleration in the village is about 0.059 g. For stone houses, the main advice is to check the roof, how walls and beams are tied together, and damp.
The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality and the report links each address to its parcel. In an Alpine valley, slopes and mountain streams matter, so the report checks the official landslide and flood maps at the address.
