When you leave the main road from S. Sofia to Campigna, just before Corniolo, you turn right and drive into the wood.
Slow down to enjoy the wood environment first and then the landscape: it is never the same and it will astonish you at every corner.
If you drive slowly it is not uncommon to see wild animals. It will take about 20 minutes for a 7-km drive along a cobbled road to reach Badia di Sasso where the road ends.
