I'm planning to stay some days at Siena. I would like to explore a little bit the area around this city using the public transportation system. I've noticed a bus from the Tiemme SpA company going from Monte Amiata Scalo to Montalcino. I've also seen at Google Maps that there is a bus stop at Castelnuovo dell'Abate, quite near the Sant'Antimo abbey. However, I'm not sure if the bus stops there because this stop doesn't appear at the timetable provided by the company website. Does anybody know?
According to Google Maps the P1 line passes through that stop. You can see if you select the public transport option, it lists many more stops.
I regularly use Google Maps to take public transports in Italy so I'm pretty confident that it's correct, and in fact you can see a reference to sienamobilità. In any case you should probably ask for confirmation to the driver when you take the bus.
Finally, I went there, so I can now assure that the bus really stops there. I discovered that, in general, buses from Tiemme SpA company do have many more stops than the ones showed at the timetables that you can find at the company website. This bus stop is ideal to go from Montalcino to the Sant'Antimo abbey by walk, a very nice stroll, and then return to Montalcino by bus.
