From loc. Gallina, the trail leaves next to the contrada and continues then in a chestnut tree woodland, developing flat along the northern winding slope of Colle Bastia.
The trail, easy and suitable for easy family walks, develops along the old aqueduct supplying Città Alta, whose structure is still visible, although in decay.
Trail 912 reaches then via Ramera where it enters the road at an old fountain situated on the opposite side.
