Alta Via 1 conditions

Last updated . Satellite imagery from 5 November 2026 to 8 November 2026.

Alta Via 1: 86% snow-free as of 8 November 2026.

  • 86% of the line snow-free
  • 20.8 km still under snow
  • Snow line: 2,250 m
  • −6 points on last week.

The Alta Via 1 usually opens late June, once the high cols melt out and the huts open.

This year the line was first 95% snow-free on 6 June 2026, and autumn snow returned by 24 October 2026.

The latest satellite reading, from 8 November 2026, shows 86% snow-free.

Sentinel-2 satellite imagery from 5–8 November 2026 shows 86% of the Alta Via 1 line clear of snow, with about 21 km still under snow.

That is 6 points less snow-free than the week before, so fresh snow has fallen.

The snow line sits at about 2,250 m.

Snow remains on stages 2, 3, 4, 7 and 8; the rest of the route is clear or nearly clear.

Less snow than the same week in 2025, when the route was 79% snow-free.

What it means: Expect continuous snow from about 2,250 m. Micro-spikes and poles are recommended above that height, and an ice axe on steep north-facing traverses.

How this is measured

The route is sampled every 200 m along the classic stages. Each point uses its most recent cloud-free satellite view from the 10 days before the update.

A point counts as snow when Sentinel-2 classifies it as snow or its snow index (NDSI) is high. Cloud, shadow and no-data pixels are left out.

Imagery: Copernicus Sentinel-2 L2A (Earth Search STAC), 20 m. Elevation: Mapbox Terrain-DEM v1 (zoom 12).

Satellite snow cover is a planning aid, not a safety verdict. It cannot see snow under trees or thin new snow, and it says nothing about avalanche danger, cornices or ice. Check with huts, guides and local bulletins before you go.
