Sentiero 313: Spiazzi di Boario - Val Sedornia (sentiero 309)

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. Follow this road in the thick fir forest which continues northwards by numerous ups and downs (but without large differences in height ) and which leads into Sedornia valley, remaining substantially at the same altitude. By this path, you enter Sedornia valley, and you will cross path n° 309  that goes up from the hamlet Tezzi (at an altitude of ab. 1210 m).
