The Barma refuge is located at an altitude of 2060 meters in the Mont Mars nature reserve, located between the Biella area and the Valle del Lys in the Aosta Valley. The stone structure is built around the mountain rock in the center of an amphitheater overlooking the lakes of the same name at the foot of the Mont Mars massif (2600 m). The refuge is recently built and has a large bar, two dining rooms, eight bedrooms, five of which sleep 8, two sleep 4 and one double with bathroom. The bathrooms are shared.

The structure is equipped with solar panels for the production of electricity, integrated by a system of co-generators. The water is captured deep in the lake and treated with a water purifier so as to avoid the use of packaging to be disposed of.

From Pont Saint Martin take the Gressoney valley regional road and after the village of Fontainemore continue for one kilometer to the bridge on the right. After turning, follow the signs for Coumarial, where you can leave the car, or for Pillaz.

From both these locations you can reach the hut on foot.
