Hiking - The Rifugio Garelli loop
Undoubtedly one of the most interesting routes in the Park, through very varied surroundings, from the spruce woods at the beginning to the stunning limestone walls of the Marguareis massif, ending with rolling pastures at Gias soprano di Sestrera.
From Pian delle Gorre take the dirt road closed to traffic that goes into the Vallone del Saut.
Ignoring various branches and paths, you go up the dirt road to its end, near a small clearing, where you take the mule track to the Garelli Refuge on the left.
The mule track climbs steeply for a long time with a number of hairpin bends; when after a wooden bridge it levels out, it brings you to Rifugio Sestrera sottano (1341 m, 1:00 hour from Pian delle Gorre, fountain).
Leave the trail to the left that goes up to the Garelli refuge via the Vallone di Sestrera (shorter way) and carry straight on towards the Vallone del Marguareis. The path passes a beech wood, crosses the stream, then finally comes out of the woods.
Continue with a long traverse amid large boulders in the pasture, ignoring the junction on the right for the Colle del Prel.
Steep ascents alternate with flatter sections leading first to Gias soprano del Marguareis, then to the Laghetto del Marguareis (1924 m, 1:50 hours from the Rifugio Sestrera sottano).
Cross the small emissary of the lake, now climbing up the left side of the valley. With various ups and downs at half-way the path takes a path almost backwards. After crossing a ridge you enter the Vallone di Sestrera at Pian del Lupo, where the Rifugio Garelli appears (1966 m, 0:20 mins from the Laghetto del Marguareis).
From the refuge, take the path that descends west-northwest to Gias soprano di Sestrera below. Continue downhill, initially with narrow stony switchbacks.
When you enter the spruce wood, the hairpin bends lengthen slightly but remain quite steep. The descent continues for a long time through the woods, until you come out into the sun at the clearing by the Rifugio Sestrera sottano (1341 m, 1:05 hours from Gias soprano di Sestrera), already passed by on the way up. From here you return to Pian delle Gorre (1032 m, 0:45 mins from Rifugio Sestrera sottano) retracing your steps.
