IV, 600m, 6 - 9 hours. An amazing, varied route which should be high on the list of any climber, regardless of their ambition or ability.Approach - From the Helbronner lift, go to the foot of the north face of the Aiguille du Toule and continue past the Tour Ronde. Continue west as if heading for the Kuffner Ridge before branching off rightwards into the Cirque Maudit and heading straight for the Col du Diable approach couloir. Enter this on the left and then traverse in to the couloir proper.It is also possible (but 60 - 90 minutes longer) to approach from the Refuge des Cosmiques.1) Climb the couloir (45 degrees) to reach the Col du Diable. There are several variations on this, which will be more or less appealing depending on conditions. The traditional and most common approach is shown here.2) Scramble easily around the Corne du Diable on the left to reach the Brèche Chaubert. From here it is possible to climb the Corne via some grade 3 scrambling up its west ridge, before returning to the Brèche by doing a 30m abseil.3) 5a. Climb the Pointe Chaubert via the east ridge. There is a slabby section on this which may feel tricky in big boots, although the climbing is only 5a. 4) Make 2 x 30m abseils down the northwest face of the Pointe Chaubert to reach Brèche Médiane, directly below the Pointe Médiane.5) 5b. Move up and right along a ledge system for 20m to the foot of a 40m corner. Follow this (5b) to a spectacularly perched ledge. Step left and go through the 'letter box' gap to reach the summit of the Pointe Médiane. 6) Descend back to the 'letter box' and make an awkward 30m diagonal abseil to the Brèche Carmen.7) 4b. Just to the right of the crest of the Pointe Carmen east ridge is a wide crack. Climb this (4b) and continue up blocky ground for 10m then traverse rightwards beneath the first summit of the Carmen to reach a gap between the two summits. 8) Climb the second (western) summit and descend easily to a ledge 10m below the summit, looking down to the Brèche du Diable. Make 2 x 30m abseils down a chimney and broken ledges to reach this and then follow the ridge crest over straightforward but exposed ground to reach the foot of the Isolée. It is not necessary to climb the Isolée. If you want to avoid it, downclimb the 10m couloir in the next section before climbing up and right across broken ground to the Brèche d'Isolée.9) 5c. Downclimb a 10m couloir under the north face of the Isolée before climbing cracks (4c) on the north face to a big overhanging flake. Avoid this on the left (5c) and gain a ledge via a short corner. Continue up a flake and corner (4c) to the top. Abseil 30m down to the Brèche d'Isolée.10) Stay just to the right of the ridge crest over interesting but not overly technical ground to reach the final step. At the foot of this, move right over some suspect rock and then come back left and follow easy ground to the summit of the Tacul.Descent - Walk down Mont Blanc du Tacul's North Face and then continue back to the Aiguille du Midi. © Rockfax
