Routes

Designated as the ideal starting point, Piazza Castello in Chiavenna marks the beginning of the trail. From here, take Via Maurizio Quadrio and, just before reaching the bridge over the Mera River, turn right onto Via Poiatengo. This scenic route winds between the river, woods, and cliffs, leading to Prosto di Piuro. Highlights of this charming village include the many traditional “crotti” (natural cellars), the Church of the Assumption, and a local workshop specializing in the crafting of soapstone.
From the church square, a steep stepped path to the left of the church leads into beautiful woods, where you’ll find the first signs of the ancient soapstone quarrying activity—open-air quarries that are among the oldest in the area. Higher up, the glacially smoothed rocks feature fascinating prehistoric engravings.
Once you reach Passo Capiola (489 m a.s.l.), you have two options for the descent to Chiavenna:
The left path is easier, passing through a small valley with lovely clearings.
The right path ascends to Sasso Dragone (520 m a.s.l.), offering a closer view of the glacial erosion formations that give the nature reserve its name.
Detailed descriptions of the main points of interest are provided on the many interpretive panels along the route.
