The Via Francigena, the historic walking route from northern Europe across France to Rome, is just over an hour away from San Sano, near San Gimignano.
Today’s 3,000 km Via Francigena is a walking and cycling route joining Canterbury in England with Santa Maria di Leuca in Puglia, at the southern tip of the heel of Italy. The route features an incredible variety of landscapes and history.
