There and back of La Minute Nécessaire de M. Cyclopède, on the boulder of red n°4 and black n°19, just under the blue path. Start with the two hands on the good hold on the right face, traverse on crimps, cross black n°19, continue on the second face above a small boulder up to a good horizontal hold, come back and exit completely right as for Les 30 Secondes de M. Cyclopède.
