Lake della Vacca and the Colle del Sabbione

The route requires a very long "preamble", on a dirt road up to the Gias Valera. The route then proceeds on an excellent mule track, which turns into a footpath only as it reaches the Colle (pass).

The most interesting part of the excursion is the portion above the Gias Valera. Lake della Vacca is quite lovely, nestled in a grassy bowl, as is the Colle del Sabbione pass, where the difference between the steep rocky crags of the Italian side and the softly rounded grassy slopes of the French one can be clearly appreciated.

2 points of interest

  • Fauna

    Brown trout

    Culturally we have always considered fish to be animals very different from us, so much so that even today they are the only animals that can be hunted in a protected area. Something is changing and in recent years there has also been an interest in local forms, genetically distinct from populations of other valleys if sufficiently isolated over time. This aspect also contributes to increasing the biodiversity of a natural environment and slowly local strains are being selected which, at least in their livery, are distinguished from the typical shape of the brown trout.
  • Fauna

    The black woodpecker

    The return of the forest and above all the aging of forest environments, possible only following the massive abandonment of the mountain by past generations, has also had the beneficial effect of the expansion of species that were reduced to a flicker, at least here in the Western Alps Italian. The black woodpecker is perhaps the emblem of this comeback. Adaptable species from the food point of view but at the same time demanding as regards nesting, it is now possible to observe it almost everywhere in the woods of the park.


From the car park at Ponte di Porcera (1078 m), follow the dirt road that climbs southwards through the woods, on the hydrographic left of the Bousset torrent. Keep to the road, ignoring various branches on both sides, up to the Ponte del Suffiet.
Beyond the bridge, the road continues slightly uphill in the beech forest. You overlook two crossroads on the right: the first for Gias Blin and, a little further on, the second for Gias d'Ischietto (1357 m, 1:05 hours from Ponte di Porcera).
The cart track now climbs more decisively, enters the Vallone del Sabbione, reaches the banks of the stream and ends at Gias Valera.
At a crossroads not far from the gias, ignore the path that continues straight for Passo della Mena and go down to the right to cross the stream on a wooden bridge.
The track then gains Gias dell'Adreit (1643 m, 1:05 hours from Gias Valera).
Now on the path, you cross pastured slopes for a long time, then you go up a ridge with a few bends, and you arrive at the basin where the ruined Gias della Culatta is located.
Descend towards the center of the basin, ford the stream and climb steeply in hairpin bends on the orographic right side of the valley; it then turns south-west, traversing with minor slopes among shrubby vegetation up to the grassy hollow of Lago della Vacca (2260 m, 2:15 hours from Gias dell'Adreit).
Near the lake, ignore the path to the right for Colle del Vei del Bouc, and go up the few easy bends that lead to Colle Ovest del Sabbione (2328 m, 0:10 hours from Lago della Vacca).
