From La Fetiuere over Bernex go to the Chalets d'Oche (alpine pasture, delicious cheese and water spring).
Pass near the Lac de la Case and go to the Col de Planchamp. Climb a breach and go across a leaning flagstone (chains secure this exposed passage). Then over unstable gravels to the final crest, short but aerial. Return by the normal route (refuge de la Dent d'Oche, taste the "fondue" !!).
