Fontaine du Couzillou is a ferruginous mineral spring near Ax-les-Thermes in the Pyrenees, whose waters are naturally rich in iron, giving them a distinctive reddish tinge and a characteristic metallic taste long associated with invigorating and tonic properties in European spa tradition. Iron-rich springs like this one have historically attracted visitors seeking the energising qualities of naturally mineralised water, and the Couzillou fountain continues to draw those drawn to the character of genuine mineral springs. The spring is a quiet testament to France's extraordinary diversity of mineral water sources set against the dramatic backdrop of the Pyrenean landscape.
