From the Dent Blanche hut, climb the ridge to the east, initially on the right and then back on the left to reach a snow ridge. Climb this onto a wide, snowy col called the Wandfluelücke. Hang a left and head up to the foot of the Dent Blanche South ridge proper.

Scramble up moderate terrain just left of the ridge crest to reach the first major obstacle on the route, the Grand Gendarme. There are 2 options to deal with the Grand Gendarme -

a) Climb the west face of the Grand Gendarme via 3 pitches up to 4b rock

or

b) Traverse to the left (west) of the Gendarme and then scramble via a snow/rock gully back onto the ridge crest on the far side of the Gendarme. There are some belay stakes in the gully to aid your passage. This option is much more popular than climbing the Grand Gendarme.

Once back on the ridge crest go up a cracked slab to the foot of a slabby tower. Climb directly up this (3b) for 40 metres or (if conditions are snowy) then traverse right across ledges and then rejoin the ridge via a steep groove.

You soon encounter another step which is climbed on its right, and then an exposed but easy section right on the narrow crest of the ridge. Climb the next step just to the left of the ridge crest to a little notch then go down slightly and traverse left to a rounded slab, which in turn leads to a corner.

Drift left across ledges and then stick to the ridge crest over fun, moderate terrain all the way to the summit. Reverse the route, mainly by downclimbing and also making the occasional abseil on the trickier sections.
