Long traverse on three faces on the big boulder just after the "Drei Zinnen", in the North-West part of the sector. Start at the arete of L'Angle Découpé to the left of a big flake, traverse via blue marks, pass the angle of Beauté Divine over a corridor and exit at the end of the third face with low pockets.
Update: it is possible to end at the beginning point (this does not modify the difficulty).
