Up the wide chimney - then follow the ridge with pitches up to IV but mostly III
The route is in the vicinity of the Les Bans hut. Having crossed the Ravin Coste-Counier, the route takes an obvious wide chimney/gulley for a number of pitches scrambling/diff/type with a lot of loose rock before arriving at a small brèche. From there the route follows the ridge up left, NW, over a series of towers, the first at 2829 metres, linked by rappels, to the main summit at 3025. The rock is sound and well bolted over the more delicate sections.
