On the trail
The morning out of Usciolu delivers one of the GR20's most curious landscapes: the Arête a Monda, better known as the 'arête des statues' — a long granite ridge weathered into towers and silhouettes that genuinely do look like a procession of stone figures. The trail threads between and over them, more playful puzzle than serious scramble, and from the crest you can sometimes see the sea on both sides of the island at once.
Then the mountains simply exhale. The path drops through Bocca di l'Agnone onto the Coscione plateau, an unexpected upland of grassy meadows, meandering streams and pozzines cropped short by free-ranging horses, pigs and cattle. After ten days of granite, walking on soft turf feels faintly illegal. Streams provide paddling and bottle-filling opportunities before the easy final stretch to the bergerie-refuge at Matalza, 1,460 m, dozing among the pastures. It's one of the shortest days of the whole traverse — under four and a half hours at a classic pace — so let it be slow: this is the GR20's designated deep breath before Monte Incudine tomorrow.
Start / end
The best-stocked refuge on the trail — charcuterie, cheese, beer, and stunning sunset views from the ridge at 1750 m.
