From Rifugio Balma, follow path 415 , which climbs towards Monte Robinet and climbs up to the Fontana del Lupo , or Fontana del Diavolo (2360 m), the last guaranteed opportunity to replenish drinking water.
The path continues up a gentle slope, under the steep walls of the summit of Robinet, up to a series of narrow hairpin bends that lead to Colletto del Robinet (2635 m).
From Colletto del Robinet, the itinerary continues along path 341 which descends Val Chisone, until the wide glacial terrace (seasonal spring water nearby) and tackles the rocky step below (Graded “For Expert Hikers Only”, section equipped with chains).
In the middle of the gully, after a small pool fed by the runoff from a faint stream, the path forks: leave trail 341 on the left, which descends to Prato del Colle, and continue on route 366 , which still descends into the gully and then turns right to follow the flat valley floor of Vallone di Rouen .
After a climb and a long, high traverse, the path descends rapidly along the crest of Costa di Glantin.
Leaving the crest, cross the Vallone delle Vallette and head past the two forks for the hamlet of Seleiraut and Colle di Prà Reale (2529 m). Then proceed northwards, still on path 366, which affords splendid views of the valley floor of Val Chisone, the ridge of Val Germanasca and Monviso in the distance. The trail then climbs slightly to Lago Laus (2274 m), where there is a small building, which serves as a park warden’s hut and a bivouac hut open all year. From here, descend along path 339A, which then merges into path 339, and reach Rifugio Selleries, surrounded by alpine meadows that are also home to a number of bergerie (alpine dairies) where the renowned Plaisentif cheese is produced.
