I visited this WHS in August 2013 and decided to take it easy to be able to enjoy the panoramic views, tiny villages, wineries and good food. I decided to base myself in San Quirico d'Orcia which is central to most interesting sites in the valley. I visited several places such as Castiglione d'Orcia, Rocca d'Orcia, Montalcino, Monticchiello, Montepulciano, La Foce, Chianciano Terme, Bagno Vignoni, Bagni San Filippo, etc. There is truly something for everyone here: food, wine, medievil cities, churches, art, thermal baths, hiking, photogenic landscapes, etc. I used to think that this WHS is rather redundant since Pienza is already inscribed on its own but I have come to think that it really deserves its status as a WHS and it really has an OUV if only you give it enough time to impress!
