Long traverse (15m approximately) on the South and Easr faces of the boulder of La Dalle aux Pigeons. Start in the middle of the South face from a big boulder on the ground with the two hands on the ledge, traverse to the right, pass Le Nid de Pigeon (red n°22) and then a small angle with pockets, follow the ledge on the East face and exit in a small conch with two characteristic bidoigts 2m before the angle.
