Bormio, spas, the Stelvio and Olympic slopes in upper Valtellina
Bormio is the main town of upper Valtellina, well over a thousand metres up, in an open basin at the foot of the mountains of the Stelvio National Park. It lives on tourism all year round: skiing in winter, with the Stelvio run that hosted the men's alpine skiing events of the Milano Cortina 2026 Winter Olympics, and in summer the Stelvio Pass road and the thermal baths, known since ancient times.
This is the market of a mountain resort, with flats in apartment blocks and residences, historic houses in the centre, mountain chalets and many second homes. Anyone planning to live here permanently should weigh winter access, heating and the distance from larger services: the railway ends at Tirano, and from there you continue by car or bus. Average declared incomes are above the average for the province of Sondrio.
In 2023 there were 3,939 residents, down 2.4% on 2011, according to Istat, the national statistics office. The average age is 47.7 against 46.8 for the province, over-65s make up 28.0% and foreign residents 4.9%. By population, Bormio ranks 12 among the 77 municipalities of the province.
Bormio is in seismic zone 3 of the Civil Protection classification, like 64 municipalities in the province, and expected ground acceleration is about 0.106 g. In mountain houses the roof and snow load, insulation and systems matter more, as this is climate zone F, the coldest.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps and the report finds the plot from the address. In upper Valtellina, landslides, debris flows and avalanches are real hazards on the slopes and along streams: the report checks them on the official maps for the exact point of the house.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
