High Route 2 — Stage 4: Promoud → Planaval

From Promoud bivouac, climb to Col de la Crosatie with its famous stone steps, then descend toward Lac de Fond and Planaval.

Short but intense: the Col de la Crosatie (2,829 m) is earned up steep grassy slopes and a final fixed-rope section, exposed enough to demand care. From the pass the eye takes in the whole Valgrisenche; the descent passes Lake Fond, a glacial jewel beneath the Becca di Tey, before dropping to Planaval among irrigated meadows and stone chalets.
