Alta Val Seriana
Start from Lizzola (1259 m) and take the forest road that goes up Bondione valley. After the first stretch of the valley - that is almost flat - the path climbs more steeply (pay attention at a short stretch of rocky plate equipped with chains) always on the left orographic side of the stream, up to the intersection with path n° 304 (1620 m – Central-Eastern Orobie Trail / Sentiero delle Orobie Centro-Orientali).
Just before reaching Rusio (921 m - a hamlet of Castione della Presolana), before the bridge, follow the forest road on the left. Shortly after, leave path n° 318 on the right and begin to climb following - for long stretches - such forest road, which leads to “Pozzetto” hut and to “Malga del Campo” hut (1520 m). Continue for a few minutes along the path that leads to Olmo Hut, keep left and move up the steep meadows northwards, until you reach the ridge overlooking the Valzurio valley.
Starting from Gromo, go up to the Boario village and continue on the road that leads to "Spiazzi" for about 1.5 km. Arrived at a hairpin (just before - on the left - you passed a grocery store) take Roccolo street (on the left) and, after a few meters, a forest road and path n° 313 (about 1070 m) begins.
