The Soria Ellena Refuge

After San Giacomo di Entracque (1226 m), shortly beyond the park hiking refuge, the road becomes unpaved and, with a few switchbacks, rises up into the Vallone della Barra.
The beech woods rapidly thin out and give way to lush meadows interspersed by occasional patches of brush. The trail continues to climb at a mild gradient, near the valley floor; passing to the right of the Gias Isterpis, recently restructured, the trail continues on a long traverse until it reaches Piazzale dei Cannoni, where it passes by a mule track on the left leading to the Gias della Siula.
The road climbs with two switchbacks (shortcut possible here), then proceeds, alternating traverses and occasional switchbacks: at about 1650 m, next to a switchback heading right and at the foot of a rocky outcropping, there is another small path leading off to the left, easy to see but a bit difficult, that shortens the route.
After passing the narrow bottleneck known as the Passaggio di Peirastretta, the steepest part of the trail is finished: passing by the trail for Colle di Fenestrelle on the right, the dirt road fords the Gesso della Barra torrent at the mouth of the Piano del Praiet plateau.
Hikers should cross the torrent on the wooden footbridge, a few meters to the left of the ford. On foot, it’s best to cross the stream via the wooden footbridge on the left, a few meters before the ford. Immediately past the footbridge, the dirt trail resumes and stretches southward through the wide pasture basin of Piano del Praiet until it meets another branch of the stream, right at the fork to the right leading to Colle di Finestra and Pera de Fener. 
The track fords this stream as well and, turning sharply northward, climbs up the hillside to the Soria Ellena Refuge (1840 m, 2 hours and 15 minutes from San Giacomo di Entracque).
