Sentiero 258: Rifugio Longo - Rifugio Baita Armentarga (crossroad path 208)

From Rifugio Fratelli Longo (2026 m), the path leads directly to the bottom of Mount Sasso valley. Go downhill near the creek to about height 1800 m. The path now turns left (eastward) and enters the Brembo River Valley. Going along the hillside in a sparse forest and heading upstream in the valley, you reach quickly Rifugio Armentarga (private Hut 1776 m). Ford the river and, in short time, on the opposite bank, you reach the crossroad with Western Orobie Trail (208 path)  leading to Rifugio Fratelli Calvi  (2050 m)
