Terme di Castelnuovo

Terme di Castelnuovo is a natural thermal spring destination in the heart of the Tuscan Maremma, the ancient and wild coastal region of southern Tuscany that has been home to thermal bathing culture since Etruscan and Roman times. The bicarbonate mineral waters emerging from the volcanic substrate of the Maremma are typical of the geothermal richness that characterizes this corner of Tuscany, home to some of Italy's finest and most abundant thermal resources. The spa offers classical Italian thermal treatments in a setting of Maremma countryside characterized by macchia scrubland, medieval hilltop villages, and the rolling landscape that has defined Tuscany's image in the global imagination. Terme di Castelnuovo embodies the authentic Tuscan thermal tradition — simple, mineral-rich, historically rooted, and embedded in one of Italy's most scenically and culturally captivating landscapes.
