Montagne des Mémises

Montagne des Mémises is a mountain summit in Haute-Savoie that rises above the villages of Thollon-les-Mémises and Bernex near the Franco-Swiss border. Its slopes feature layered sedimentary rock formations typical of the Préalpes médianes region, creating distinctive geological patterns visible from various angles around the peak.

This mountain formed during the Jurassic and Cretaceous periods as part of an ancient sea floor that was later thrust upward during Alpine mountain building. The layering and rock formations visible today are direct results of these massive geological transformations that shaped the entire Alpine region.

The mountain stands as a central element of the Chablais Geopark, contributing to the natural heritage of the Franco-Swiss border region.

The village of Thollon-les-Mémises at the base provides facilities and equipment for various activities depending on the season. Winter sports are popular from December through April, while warmer months draw hikers and paragliders to explore the wider area.

On clear days, the summit offers sweeping views across Lake Geneva to the Jura Massif and the Alps beyond, making it a favorite spot for paragliders seeking optimal thermals and visibility. The geological position here marks where different Alpine rock layers meet, revealing millions of years of Earth's history in the exposed stone faces.
