300m. A fantastic hard route featuring some brilliant crack climbing that isn't common in the Aiguilles Rouges. The climbing is pretty sustained providing a great challenge. Start as for Grevolle Direct. The junction is marked with a metal plaque on the bolt.

UKC Logbook Description
The hardest and at nearly 400m, the longest route on the Perrons. It starts easily enough up the first 2 pitches of Grevôle, then heads right a bit to climb the nice wall right of the corner of Grevôle. Once on the middle terraces it goes right and takes the striking thin crack in the grey wall - its raison d'être - and definitely the best pitch on the Perrons. Harder climbing follows to a superb, if easier finale up the ramp that splits the overhanging headwall. 11 pitches. Take 15 quickdraws and 2x50m.
