III, 220m. Once an undocumented line that only the locals knew about, Vent du Dragon has become something of a classic and is probably the most climbed route on this face since it appeared in Philippe Batoux's beautiful Mont Blanc - The Finest Routes book. Start in the snow bay below an open, low-angled snow/mixed ramp.
1) 3, 60m. Climb the ramp easily on snowy mixed ground and cross onto the right before coming back left where it widens. Stay on the left and climb a short mixed step to reach a bolt and some slings around a block.
2) 3+, 40m. Continue with slightly more difficulty (but still on steady ground) up a right-leaning gully which leads to a large slab. Carry on rightwards past the foot of the slab and 5m further up to reach a peg and bolt belay.
3) 5, 55m. Climb the stunning icy runnel to the right of the slab to where it is capped by a blocky overhang. Step left and turn the overhang on the left (crux) before continuing up the right-leaning icy runnel above. Climb this for 15m to a snowy col and a bolt/peg belay.
4) 5, 50m. Step right from the belay and make a couple of mixed moves to gain the icy runnel above. Climb this and then make a mantelshelf move left into another runnel. Follow this to its top and then step left into and through a cave and some tenuous feeling mixed moves to a bolt belay. Don't be tempted out rightwards by the snowy gully near the top of this pitch, it is much harder than it looks...
5) 2, 15m. Move left around the corner and climb the snow slope to reach the Arête des Cosmiques. © Rockfax
