Haut Sex

Haut Sex is an alpine summit in La Chapelle-d'Abondance that rises to just under 2200 meters. The terrain shifts between forested areas, mountain meadows, and ridge paths that extend across the landscape.

The summit has long served as a natural border marker between France and Switzerland. This geographic position made it significant in establishing territorial boundaries between the two nations.

Local mountain communities maintain traditional alpine practices, organizing regular guided tours and nature observation activities throughout the summer season.

Hiking routes are typically open from mid-June through mid-September for visitors. No entrance fees are required, so you can explore the mountain paths freely.

The mountain ranks as number 71 among 262 peaks in Geopark Chablais, demonstrating substantial prominence in the regional geological formation.
