Baños de Rioja Arnedo Spa draws sulfurous springs in the Cidacos valley near Arnedo, a La Rioja town famous for its shoemaking craft and for the prehistoric dinosaur footprints discovered in the surrounding red sandstone cliffs — one of Spain's richest dinosaur fossil zones. The mineral waters have been appreciated since Roman times within a long thermal tradition, forming part of Arnedo's enduring artisan and thermal heritage in the wine-growing heartland of La Rioja. Soaking in sulfurous pools against a backdrop of ochre and crimson Mesozoic cliffs, within driving distance of the world-famous Rioja wine bodegas, is a characteristically multi-layered Rioja experience.
Insider tip — Banos de Rioja in Arnedo draws sulfurous thermal waters from the red sandstone sierra above the Cidacos River, a valley renowned for both wine and prehistoric dinosaur tracks preserved in the canyon walls. The balneario specializes in dermatological treatments, and a visit pairs naturally with exploration of La Rioja's celebrated Denominacion de Origen wine cellars just to the north.
