Balneario Hervideros Cofrentes

Balneario Hervideros Cofrentes, at the confluence of the Júcar and Cabriel rivers in Valencia province, draws on the naturally carbonated and iron-rich 'hervideros' (effervescent springs) that bubble dramatically from the earth in a valley dominated by the volcanic plug of Cofrentes castle rising above the river junction — the same geological forces that produced the volcanic landscape also endow the springs with their distinctive ferruginous and naturally carbonated character. The iron-rich sparkling waters, used since at least the 18th century, provide a naturally effervescent drinking experience that reflects a long tradition of mineral water use in the Valencian interior. The Cabriel river valley near Cofrentes, with its dramatic rapids, protected fluvial landscape, and status as one of the cleanest rivers in Spain, provides exceptional canoe and rafting terrain alongside the thermal bathing — making Balneario Hervideros one of Spain's more adventurously positioned mineral spa destinations.
