SI D21S

From the Merelli refuge to Coca (1892 m), descend briefly towards Valbondione until reaching the small bridge and crossing the stream. Leave trail 301 that descends into the valley, and climb left, ascending the grassy slope and gaining altitude until reaching the Polledrino valley (approximately 2150 m). The path now traverses the hillside, crossing several small valleys, and after some ups and downs, arrives at the Corno pass (2220 m). Now, descend slightly while crossing very steep slopes to reach the base of a rocky gully, which is navigated (equipped section) to climb to the small plateau above. Continue along the hillside to Sponda Arsena (approximately 2350 m) to overlook Valmorta, a panoramic point, and, through a series of hairpin bends, quickly lose altitude until reaching the small artificial reservoir (Valmorta modulation reservoir - 1798 m) below the large dam of the Barbellino Basin. Ascend to the guardians' house and, skirting the Barbellino Basin for a short stretch, finally arrive at the Curò refuge (1915 m). This stage faithfully follows the Trail of the Western Orobie.
