Hauts-Forts

Hauts-Forts is a mountain summit in the Chablais Alps that stands at 2466 meters and represents the highest point of the French Prealps in this region. The peak is characterized by a ridge formation that extends roughly 2.5 kilometers with varied terrain and rock faces.

The mountain was shaped over millions of years through geological processes and consists of sedimentary rock belonging to the Brèche nappe system. This rock formation reveals how the Chablais Prealps developed through extensive tectonic activity and layering.

The summit serves as a gathering point for ski mountaineers and alpine enthusiasts who practice their sport across its slopes throughout winter and summer. The mountain's identity is closely tied to these outdoor activities and the people who come to experience them.

The ascent is manageable for experienced hikers and ski mountaineers with proper alpine gear suited to seasonal conditions. The best visiting period is from June to September for hiking and from December to March for winter sports activities.

The north and south faces of the summit show striking contrasts in development, with the north side featuring ski lifts and infrastructure while the south face remains completely undeveloped. This difference reveals how the same peak can be used in dramatically different ways depending on which slope you ascend.
