Château d'Oche

Château d'Oche is an alpine summit in the Chablais massif reaching 2,197 meters elevation. The mountain overlooks surrounding lakes and valleys in the Haute-Savoie region.

The mountain formed through geological processes that shaped the Préalpes médianes, a distinctive formation in the French Alps. The sedimentary rock layers record the changes that have shaped this mountain landscape over millions of years.

Local hiking groups regularly organize educational expeditions to study the geology and observe the alpine wildlife in the region.

Several marked trails lead to the summit, with the southern slope offering a straightforward approach. The routes are well-maintained and the climb is moderately challenging for hikers.

The sedimentary layers here read like pages of an open book telling the prehistory of the Alps. With a trained eye, visitors can observe how different rock strata reveal the millions of years it took to create this landscape.
