Aiguille de Leschaux, Mountain summit at France-Italy border, Chamonix-Mont-Blanc.
The Aiguille de Leschaux is a rock summit on the France-Italy border that rises from granite formations and offers multiple climbing routes of varying difficulty. Its steep walls and exposed position make it a popular destination for experienced mountaineers.
The summit was first climbed in the 1800s by alpinists systematically exploring the Mont Blanc group, who established multiple routes to the peak. These early ascents contributed to the development of modern climbing techniques.
The name comes from a family with long roots in the Alpine region, and locals recognize this summit as a defining landmark of the Mont Blanc group. The peak serves climbers as an important waypoint when traversing this complex mountain range.
Visitors should plan the approach from either Chamonix or the Italian side of Courmayeur and start early to take advantage of favorable weather windows. Proper footwear, a headlamp, and knowledge of route options are essential for a safe outing.
The summit lies exactly on the watershed that divides Mediterranean and Adriatic drainage basins. Water drops from this spot can flow to two different seas depending on which side they fall.
