This alternative path avoids the unpaved slope on the road that goes from San Quirico to Vignoni Alto and Bagno Vignoni, and follows the Via Cassia, that has to be traveled paying attention to the traffic. Once you arrive at the crossroads with SP 53 in Val d’Orcia we suggest you to lightly extend your way in order to visit Bagno Vignoni, its beauty deserves the deviation.
