Description
Stage thirteen is the first of the final sequence steering the Alta Via 1 toward the Mont Blanc massif: from Ollomont the trail climbs over 1000 metres to Rifugio Champillon in the Conca di By, one of the most unspoiled landscapes in the entire Aosta Valley. The route departs from the hamlet of Rey, threads through a larch and Scots pine forest on quite steep sections, reaches the summer farms of Prumayes (1621 m) and continues on a well-marked path toward the Champillon meadows. The small chapel of Notre-Dame-des-Neiges at approximately 2300 m is the spiritual landmark of this stretch and deserves a quiet stop. Rifugio Champillon (2465 m), in the Conca di By at the foot of Col Champillon, is a distinctive hut: a sauna with Alpine views, a yurt on the lawn, and a young, informal atmosphere. Dormitory accommodation and wild camping in the surrounding meadow are both available depending on preference and season. The stage is short in kilometres but the unrelenting positive elevation — with almost no flat sections — demands trained legs and a steady rhythm.

Geology & landscape
The climb into Conca di By crosses augen gneiss and micaschists of the Austroalpine basement with quartz and garnet bands. Notre-Dame-des-Neiges chapel stands on Würmian glacial deposits with rebuilt moraines and lacustrine sediments. Above 2200 m, quartzites and chloritic phyllites appear with quartz-feldspar pegmatites. Rifugio Champillon sits on a plateau shaped by periglacial deposits with scree and active solifluction. Toward Col Champillon (next stage), calcschists and marbles of the lower Penninic stack appear. Colluvial deposits and historic landslides indicate instability on forested slopes below Prumayes.
History & culture
Conca di By is an intact pastoral landscape with active summer farms. Rifugio Champillon is known for its yurt and alpine-view sauna.
