A large area of rural Tuscany, the Val d'Orcia boasts endless vinyards and olive groves spread over an undulating landscape.
A comfortable way of seeing this area is to take the Treno Natura from Siena on one of its periodic perigrinations - mostly on spring and autumn weekends. At other times the nearest station is at Buonconvento. From here I took buses to Montalcino and to Pienza. From both of these hilltop towns there are extensive views over the landscape.
