Villetta a schiera in Frazione Bulliana

The cluster is in the Biellese prealps, on the forested slopes above the Cervo and Sessera valleys. The Sessera stream and the Panoramica Zegna road are part of the immediate area, and the upper valley rises toward the Bielmonte side of the mountains. The Oasi Zegna protected area lies within this part of Valdilana and is the main named landscape feature nearby. The nearest ski lifts are at Bielmonte, roughly 20–30 minutes by road depending on the exact hamlet. Biella is the nearest town of size, with full services and a historic upper town. This area is known for the historic wool-textile industry of the Biella district and for the Zegna mountain estate.
