Morgex highway exit. Turn left towards Courmayeur and, on the straightaway, turn left again for Colle San Carlo. After 3.5 km, park near the wall sign.

Smooth granite ledges and technical pitches, a mix of climbing styles that are especially challenging in the hot summer. Anchoring is good with stainless steel resin material and fix stops with belays. The first part of the route has slightly steep and athletic pitches while the ledges are for hold climbing. There are many small sectors here with very particular and challenging routes, always on excellent rock.

Wall ascent: Follow the forest path up to a fork. Keep to your right and, near the stream, the road ends and a path starts to the base of the first routes.

The Kirriaz wall, called the Hans Marguerettaz wall, is dedicated to talented alpine guide from Courmayeur who met a premature end during a glider flight. A climber from Valle d’Aosta, Stefano Zilio, began bolting the more challenging routes. Later, the town decided to have alpine guide, Andrea Plat, anchor the route, cleaning the wall of unstable boulders and bolting the routes on the children’s ledges.
The activity requires technical experience. Alpine guide assistance is recommended.

Descent: Stops include chains and belays or Munter hitches. Climbers are either belayed down or abseil on longer routes.
