Bagni San Filippo

Bagni San Filippo hosts yet another selection of natural warm-water springs. It’s a small town, huddled onto a hillside just at the western edge of the Val d’Orcia. The steamy waters submerge the whole place in a lightly sulfuric air, which says the bathing spots are never too far away. Be sure to skip the paid thermal baths and walk straight into the forest park just a few minutes out of the center. Down a short track overshadowed with downy oaks and pines, you’ll find the so-called White Whale. It’s a hulking mass of calcium deposits that have built up from centuries of water trickles. Beneath it are the muddy spa pools. They’re free to enter and offer natural face masks next to soothing waterfalls.
