Climbing the Whymper Couloir and East Ridge
From Chamonix, France, ride the Montenvers railway and approach the Couvercle Hut, then reach this outlying summit on the Aiguille Verte's east ridge (D-), almost never climbed for itself. Standard access is the Whymper Couloir followed by the connecting ridge from the Verte, which inherits all of that couloir's rockfall exposure and bergschrund difficulty, so treat it as a cold, pre-dawn objective. It is usually collected by parties working the Verte, Grande Rocheuse and Aiguille du Jardin ridge in one outing. Watch cornices on the crest. Budget 2 to 3 days.
