Grenier de Commune

Grenier de Commune is a peak in the Chablais Alps standing around 1775 meters high and composed of sedimentary rock layers. The slopes display distinct geological strata that reveal how water and pressure shaped this mountain over millions of years.

This summit formed millions of years ago as an ancient seafloor before tectonic forces lifted it to its current height. The sedimentary layers preserve evidence of marine life that once inhabited this region when it lay beneath ancient oceans.

The name reflects a tradition of shared mountain use common throughout Alpine communities. These naming choices show how local people have organized grazing and forest rights together for generations.

Several marked trails lead from the nearby village of Sixt-Fer-a-Cheval toward the summit, with hiking easiest during the warmer months. In colder seasons, snow and ice may block or slow access, so checking conditions before you go is important.

From the summit on clear days you can see both French and Swiss Alpine terrain, since the peak sits near the border between the two countries. This position makes it a natural vantage point where the geography of both nations becomes visible at once.
