At 2020 meters, Lake Barma (or Balma) is a lake of glacial origin sunken between the Gragliasca peak, Lei Long and Balma d’Oropa on the left, Mont Mars and Monte Rosso on the right, and the Balma d’Oropa hill in front. With 31,320 square meters of extension, it is the largest lake included in the Mont Mars Nature Reserve. On its shores, from the second half of June, rhododendrons, mountain lilies, round cotton grasses, mountain arnica and wild orchids bloom.

The Upper Lei Long is a lake of glacial origin located at 1925 meters above sea level within the Mont Mars Nature Reserve and, in particular, at the foot of Mount Mars and Lei Long peak. The lake and the surrounding area have a stagnant and marshy appearance.

Very modern and comfortable refuge. Equipped with 24h electricity, wi-fi, hot water. The refuge is also a stop for the Oropa Valley walk. The Barma refuge is located at an altitude of 2060 meters in the Mont Mars nature reserve, located between the Biella area and the Lys Valley in the Aosta Valley. The stone structure is built around the roche moutonne 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 rooms, five of which seat 8, two seat 4 and a double with bathroom. The services are shared. The structure is equipped with solar panels for the production of electricity, integrated with a co-generator system. The water is collected from the depths of the lake and treated with a water purifier so as to avoid the use of packaging to be disposed of.

Recently built refuge surrounded by the Barma lakes, open in the summer and reachable with a not too demanding walk from Pillaz (or from Pian Coumarial) a hamlet of Fontainemore, overcoming a long stretch of road up to Lake Vargno

Lake located between Lake Vargno and the Barma lakes. It is not very attractive due to its marshy waters, and the path runs a few meters higher up
