From piazza Garibaldi di Chiusdino head downhill towards Ciciano and, after around 300m, turn left on the Segolino road towards a junction with the S.S. 441. Here, turn left and shortly afterwards turn right downhill on a dirt track towards Luriano and the crossing over the River Merse. After 6km up a winding hill, you will go past the church of Santa Maria di Luriano before heading downhill once more towards the ford over Torrente Seggi. From here, the road goes back uphill for around 1.5km below the twelfth-century Luriano castle.
Continue downhill towards the S.S. 73 and you will arrive at the ruins of the church of Chiesino, a place of many historic legends. Continue to the left and pass the Osteria delle Macchie where parts of the Historic Maremmana Road, which runs from Siena to the sea, are still visible. Go downhill along a rather uneven woody path, which becomes much smoother after 700m. This road, marked by the Province of Siena, runs for 15.50km and will take you to Pian di Campora, passing and crossing the Laccera trench several times (the road can be challenging in heavy rain).
