Dent d'Oche Mountain

Dent d’Oche is a mountain in the Chablais Alps in Haute-Savoie, France, rising to about 2,200 meters above sea level. It is a prominent limestone peak near the French shore of Lake Geneva.

A distinctive steep-sided summit, it draws day hikers and scramblers who follow a range of marked trails and ridge routes. The summit ridge offers wide views of Lake Geneva, surrounding Alpine ranges and, on clear days, distant Mont Blanc.

Geologically part of the Chablais Alps, the peak is formed largely of limestone and shows typical alpine karst features. The area around the mountain has long been used for alpine pasture and seasonal grazing.

The mountain sits on the French side of Lake Geneva, north of Thonon-les-Bains and near the Swiss border, within the Chablais massif. Access is typically from local valley roads and mountain trailheads.

• Summit views: The summit gives broad panoramic views of Lake Geneva and surrounding Alpine peaks on clear days.
• Routes and difficulty: Marked hiking and scrambling routes lead to the top; some sections require sure-footedness and basic alpine route-finding skills.

The peak is typically accessed from villages on the French side of Lake Geneva (Léman region); follow local alpine trailheads and signposted routes. Public transport reaches nearby towns, from which local roads and trailheads connect to the mountain approaches.

• The classic walking route to the summit passes via the Col de Cou; be prepared for scrambling sections near the top.
• In winter and spring, bring equipment for snow and potential avalanche conditions; check local alpine reports.
