The Grutter ridge is one of the classics of the Aiguilles de Chamonix Massif. It leads to the summit of Aiguille des Pélerins at 3318m.
It's an awesome route (D, 5b), rather vertical and sometimes airy. It is one of the best 100 routes described by the famous French guide, Rébuffat.
Elle surplombe l'aiguille du Peigne et est dominée par l'Aiguille du Midi, l'aiguille des Deux Aigles et l'aiguille du Plan.
Early start on a steep glacier but with no bergschrund :)
There are a few amazing pitches on this ridge, one of which leading to an impressive, isolated gendarme.
