You won't find much written about it in the tour guide books but it makes up a line of pleasant little stops along the way to visit the summit of Monte Amiata where you can picnic or simply enjoy hiking in one of the highest points of southern Tuscany. This imposing mount can be seen from distances as far away as Montepulciano.
This is a lazy little setting, and you will enjoy walking the streets and admiring the views. They are not geared up for tourism at all, so you won't find a lot of quaint little boutiques or fancy enoteca's with the latest in wine and cheese just simple good food in a typical Tuscan environment.
Though picturesque, they could have better planned the parking lot around the Renaissance church of Madonna della Carità, which literally creates an asphalt garden in the middle of the olive groves. But I guess when the built the church in the 1600's the parking lot wasn't a main concern.
