WITH CAR:

By car:
from Florence there is a highway to Siena, get out at San Casciano Val di Pesa, then follow road markings to San Pancrazio and then Fornacette and Fiano. After having crossed Fiano's village, the road has two hairpin bends and then you can see on the right the "Piviere" restaurant, just near on the left there is a little road to arrive to the country village of Luia.
