Grande Bosse

Grande Bosse is a snow-covered summit in the Mont Blanc massif at approximately 4,435 meters. It sits along the main climbing route to Mont Blanc between Dome du Gouter and Petite Bosse.

The first recorded ascent took place on July 18, 1861, led by Leslie Stephen and F.F. Tucket alongside guides Melchior Anderegg, Johann-Joseph Bennen, and Peter Perren. This established the summit as a key reference point on the Mont Blanc route.

The summit stands as a reference point for mountaineers worldwide, marking a significant milestone on the journey to reach Mont Blanc's peak.

Access is via the Bosses Ridge route starting from Gouter Refuge and requires advanced mountaineering experience and specialized equipment. Conditions are demanding and vary with season and snow coverage.

Although not among the official 82 Alpine peaks above 4,000 meters, this summit appears on the supplementary list of secondary summits. This classification makes it notable for peak baggers aiming to climb all recognized high points.
