From Siena you come to the hamlet of Arbia, where you take the provincial Lauretana (SP 438) and embark upon a first stretch of dirt track. In this stage, the Via Lauretana climbs to the peak of the biancane around Leonina, and then sticks to the crest on a clay, almost lunar-looking path. Pay attention: the clay underfoot in the rainy season is truly an experience that is not forgotten easily!
Keeping to the route, you arrive at a permanent stone installation by Jean Paul Philippe, a “Transitory Site” where passers-by can find a seat and a window angled to catch the last ray of sun on the summer solstice.
The route continues to Mucigliani, along a path that offers a 360-degree view of the Sienese countryside, right up to the start of the provincial road. Walk with care, heeding the signs that often instruct you to walk on the side of the asphalt road, and continue to the little settlement of Vescona, that was once an important castle.
More experienced walkers can continue and stop in Asciano, extending the first part of the route.
