The Anello dell'Arma is a classic loop of about 2.5 kilometres, entirely in the Le Manie area: number 17 on the Finale Outdoor Region map, an intermediate all-mountain route.
It starts from the Trattoria La Grotta, climbing on a dirt road, and after a few hundred metres it turns onto a narrower, rougher path, still uphill. From there you follow the signs over easy rolling singletrack with a few harder bits, mostly on the climbs.
The surface is typical of the area, red clay soil and mostly fixed rock: grip is usually excellent, but it gets slippery when wet or very dry. Before you set off, check on the Finale Outdoor Region website that it is open: trails close for maintenance, races or bad weather.
