UPDATE FIRST STAGE
Due to an interruption on the natural trail along the Marecchia river, it is necessary to take the easier detour described below, which is 1 km longer than the official one. Download the GPS track.
When in Vergiano, after reaching the SP Marecchiese, instead of turning right onto via Pergola (Photo 1),
Photo 1
continue straight on the cycle/pedestrian path next to the provincial road, up to Sant'Ermete (1.1 km), then at a small roundabout take Via Savina on the right (Photo 2)

Cross it on the pedestrian crossing and continue on the other side for 0.9 km (initially on the pavement), until you find Via Sarzana on the left (Photo 3)

Take and follow it all the way until it ends on Via Traversante Marecchia, in San Martino dei Mulini (1.5 km - photo 4)

Here you turn right; after passing a roundabout, cross it continuing on the opposite side, first on the pavement and then on the cycle/pedestrian path. After passing a cemetery and a plant nursery, follow the cycle path that turns left onto Via Pallada (Photo 5)

and then back on the parallel path to the Traversante Marecchia, ending in a small car park where you rejoin the Cammino route.
Those who need to reach Santarcangelo must leave the car park on their right, taking the provincial road and crossing the bridge over the Marecchia. The Cammino continues, leaving the car park on your left side (Photo 6)

from the barrier, follow the signs that lead in a few meters to the nature trail along the river, at which point you turn left and continue towards the mountain, as per the indications and GPS tracks.
