Insider tip — Terme di Petriolo in the Farma-Merse valley south of Siena is one of Tuscany's most ancient thermal sites — its sulfurous springs emerge naturally at 43°C and have flowed since Etruscan times, documented in medieval papal bulls and bathed in by Popes Pius II and Pius III. The Mercure hotel brings modern luxury to a spring that has been revitalizing Sienese nobility and pilgrims for six continuous centuries.
