Start from Curò Hut (1895 m), follow the easy muletrack and reach Barbellino natural lake (2188 m). Along the left bank (north) of the lake, climb along Serio river then, at an altitude of about 2300 m, the path curves to the right (east) pointing to the wide saddle of “Grasso di Pila” Pass (also called Barbellino Pass). Going up, you go along the pretty "di Pila" ponds (ab. 2350 m), finally reaching the pass.

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).
Starting from the garage of “Autolinee SAB” bus lines, placed on the left at the beginning of Valbondione (870 m), climb through the woods towards "Salvasecca" farmhouse. Leave it on the left and continue the ascent until you meet a forest road that you have to follow for a certain distance. The realization of such road has modified, in part, the old route. It is important to pay attention to the white-red signs (especially downhill) to follow the path correctly.
Leave Coca Hut, go up the valley and reach Coca lake (2108 m). Just before the lake, continue right (east) going up a steep scree and a little canyon by an easy climbing. Continue the ascent on easier (but still steep) terrain, until to reach “del Polledrino” notch, under the southern rib of Pizzo Coca peak and then cross a basin leading to the overlying “del Camoscio” notch (2719 m - attack point of the alpinist climb to Pizzo Coca peak).
