The starting point is the village of San Martino, with the "Gigiàt" on the wall of a house welcoming you. The trail - marked by a brown sign - "for Val di Mello" starts beyond the houses of Via Vanoni and is in the woods, on the orographic right at the stream. The second detour on the left side of the trail is to follow to reach the road near a small chapel.
The locality of Ca' dei Rogni (M 1,019) with the Ferro waterfall mark the "real" entrance to Val di Mello, which after the parking lot in the locality of Ca' Panscer (M 1,061) is even more natural, with no traffic. The points of interest are indeed many; certainly for those who walk this route, the Qualido pond and the Bidet della Contessa, in dialect known as Burgùn, are worth mentioning - in order of passage. The Contessa - according to legend - was a young woman who loved to cool off in these waters. The localities - groups of stone houses - are all well integrated into the landscape and are: Ca' di Carna (M 1,076), Cascina Piana (M 1,092) with the peculiar hut "leaning" against a large boulder, and Rasica (M 1,160), the last nucleus on the valley floor.
The return follows the same route.
