The Refuge is located at the foot of the Marguareis, near the Colle dei Signori, High Tanaro Valley, in the municipality of Briga Alta (CN).
Due to its special geographical position in which it is located, the refuge Don Barbera can be reached from 5 main access streets, positioned in a radial way: Carnino (Tanaro Valley), Limone Piemonte (Vermegnana valley), Tenda (val Roja), Chiusa Pesio (Pesio valley), Rastello (Ellero valley). This allows a wide variety of hiking, walking and links from multiple starting points.
Road access: from Torino-Savona motorway exit at Ceva, then climb the Tanaro Valley to Ponte di Nava, where you take the right crossroad for Viozene, Carnino and Upega. Before the bridge over the Rio Carnino is the detour for Carnino. In Carnino Superiore (Superior Carnino) you leave the car (parking).
Having a off-road vehicle, Colle dei Signori can be reached from Monesi (the head of Val Tanaro) or the Colle di Tenda (the head of Val Vermenagna) with a bold and exciting street ex-military. The road is currently closed due to Rebuilding that will last throughout 2013.
