Montepulciano parking if coming from Siena
 

I keep reading about parking outside the Montepulciano town walls, at the "foot of the hill" --- Can anyone tell me where this in in terms of street intersections or GPS coordinates?

I am preloading my GPS with coordinates for parking and not sure which Montepulciano parking area is best if I am coming from the north/east, from Siena direction.

Thank you!

Not sure which route you will take, but if you d/l this map and then click to enlarge a couple of times you will see all the parking lots. Last time I was there, I parked near the tourist office and found a free spot.

There is also a bus that runs through the center.
