Climb Aiguille Verte 4122m via Whymper Couloir
Introduction to Aiguille Verte: An Iconic Peak of the Mont Blanc massif
With an altitude of 4122 meters, the Aiguille Verte is one of the most significant and historic mountains in the Mont Blanc massif. Known for its breathtaking beauty and challenging climbs, it offers unforgettable summit views that reward those who brave its demanding routes.
Why Climb Aiguille Verte via the Whymper Couloir?
The Whymper Couloir is the most elegant and obvious line on the southeast face of Aiguille Verte. This classic alpine route was first partially ascended in 1865 by legendary climbers Christian Almer, Franz Biner, and Edward Whymper. It remains a bucket-list climb for mountaineers visiting Chamonix.
Technical Details of the Whymper Couloir Ascent
Although not overly technical, the climb is long and sustained, with slopes between 45° and 55°. The southeast orientation means much of the climb is done at night, allowing climbers to reach the summit for stunning sunrise views over the Mont Blanc range.
Two-Day Itinerary: Approach, Summit, and Return
This iconic climb is typically completed over two days. The first day involves the approach hike to the Couvercle Hut, providing a perfect base. The second day is dedicated to summiting Aiguille Verte via the Whymper Couloir, followed by a safe descent back to Chamonix.
