On the broad boulder just left of Tas Réta Tas, in a small chaos behind the classical area of Cuvier Est, underneath the North ridge. Standing start on the left at the tree, traverse on slopers and exit at the holly.
Traverse the classical sector of Cuvier Est by La Route de Bellevue and continue up to the GR. Follow the GR on the right for 100m up to a big bend to the right. The boulders are just before, 30m on the left up the hill.
