Bagni San Filippo
Medieval pilgrims walking the Via Francigena from Canterbury to Rome loved pausing in this part of central Tuscany to enjoy a long therapeutic soak in its thermal springs. If you're keen to do the same, consider avoiding the famous thermal institute in Bagno Vignoni and instead head to the open-air cascades in this tiny village 16km southwest of Pienza. You'll find them just uphill from Hotel le Terme – follow signs to 'Fosso Bianco' down a lane for about 150m. Your destination is a series of mini pools, fed by hot, tumbling cascades of water. A free al fresco spa.
