Tuscany Thermal Baths Day Escape

The thermal springs at Saturnia have been flowing from the same volcanic source for thousands of years, and the Cascate del Mulino — a series of natural travertine pools on the Gorello stream just below the town — remain free and open to anyone who arrives at the water's edge. This day escape from Siena covers the 90-kilometre drive south through the Maremma, Tuscany's least visited and most sparsely inhabited province, arriving at the pools in mid-morning before the midday crowd. Participants soak in water that emerges at a constant 37.5 degrees Celsius and carries high concentrations of sulphur, carbon dioxide, and minerals that have been used for therapeutic purposes since Etruscan and Roman times. The guide walks the group through the geological background of the Saturnia caldera and the history of the spa town above, which still contains Roman-era walls and a small archaeological museum. The itinerary includes time to visit the hilltop village of Saturnia itself — the medieval church, the Etruscan gateway stones set into later Roman construction, and a local trattoria for lunch. The afternoon returns to the lower pools for a second soak as the light shifts and the steam from the water becomes visible against the hillside. Bring a swimsuit, flip-flops for the rocky approach to the pools, two towels, and old clothes you don't mind smelling faintly of sulphur on the drive back.
