The Thermes de Sainte-Marguerite are located in Puy-de-Dôme, in the Auvergne-Rhône-Alpes region of France. The spa offers iron-rich thermal water at around 38°C, with indoor and outdoor pools, sauna, hammam and massage treatments.
Insider tip — Thermes de Sainte-Marguerite draws iron-bearing chlorinated waters from the volcanic Auvergne subsoil at 38 degrees, a combination prized for treating anemia and phlebological conditions within the Massif Central's rich thermal tradition. The small establishment sits amid the rolling Puy-de-Dome countryside away from the larger spa towns, offering a more intimate and rural cure experience. The surrounding Auvergne volcanic peaks and medieval villages provide excellent exploration between sessions.
