About Passy — Barmus

The harder of the two Plaine-Joux limestone crags — bolted routes 5b–7a on south-facing slabs and short vertical walls. Chairlift access in season shortens the walk-in significantly. Same fast-drying dolomitic limestone as neighbouring Larses; same Mont-Blanc view. Bring stiff shoes — Passy limestone rewards precise footwork.

Region: Passy
Rock type: Limestone
