This track allows the connection between the M. Secco lower hut (1395 m, reached from Cerrete - a hamlet of Ardesio - by the path n° 264) and the path n° 241, which reachs M. Cima Vaccaro and the homonymous huts.
Reach the so-called “Il Pozzo” ENEL (1800 m, an odd hydraulic build) along path n° 331 that climbs from Valbondione. Climb in the valley along the fall line and - at 2100 m - turn left (west) reaching, always in steep terrain, the plain that is home to “d’Avert” lake (2310 m). After crossing the lake, begins to rise again through the path traces on rough grazing.
The path starts from the Coca Refuge (1892 m). In the first part, the track is shared with the path n° 302 and you rise the valley until you reach the lake of Coca (2108 m). The trail runs along the lake, passing it and begins to rise with increasing slope – by tracks - along the big scree descending from Coca Pass (2645 m).
