Mont Dolent 2-Day Three-Border Peak Expedition¶

Two-day alpine ascent to the France-Switzerland-Italy triple border summit at 3,820m in the Mont Blanc massif — mixed terrain, glacier, and a unique three-country panorama.

Overview¶

Mont Dolent (3,820m) is a unique geographic landmark: its summit is the precise triple-border point of France, Switzerland, and Italy in the Mont Blanc massif. The 2-day route from La Fouly in the Swiss Val Ferret approaches via the Cabane du Trient SAC hut (3,170m) to the Col du Dolent and Northeast Ridge. The summit day involves mixed terrain and a short section of moderate alpine ice. Three countries are visible simultaneously from the top. An IFMGA guide is advisable for those without prior alpine experience; more experienced alpinists can ascend independently with correct glacier travel equipment.

Day 1: La Fouly to Cabane du Trient¶

From La Fouly village in the Swiss Val Ferret, ascend through alp meadows and moraine to the Cabane du Trient at 3,170m. The hut is owned by the Swiss Alpine Club (SAC) and offers excellent meals. Afternoon acclimatization walk and gear check. Panoramic views toward the Grand Combin massif.

Day 2: Cabane du Trient to Mont Dolent Summit and Return¶

Pre-dawn departure across the Trient Plateau glacier to Col du Dolent at 3,594m. The Northeast Ridge from the col involves mixed rock and ice climbing of moderate difficulty. The summit at 3,820m places one foot each in France, Switzerland, and Italy. Return fully to La Fouly via the moraine descent.
