Balneario de Grávalos is a thermal spa located in the municipality of Grávalos in La Rioja, Spain, where mineral spring waters emerge in the semi-arid hills of the Ebro basin south of Arnedo, offering a traditional bathing retreat in one of Spain's most celebrated wine and cultural regions. Grávalos is a small Riojan village set among eroded hills and vineyards, and its balneario represents the enduring tradition of rural Spanish spas that have welcomed local communities for generations. The mineral waters and classical bathing facilities sit within the landscape of La Rioja's inland valleys, far from the region's better-known wine trails.
Insider tip — Balneario de Gravalos is a traditional Spanish spa in the Cidacos valley of La Rioja at approximately 42.6°N, where sulfurous springs have been used since Roman times. The local geology of Mesozoic carbonates and evaporites produces water rich in hydrogen sulfide. The balneario follows the traditional Spanish spa model with supervised wellness programs. Gravalos village, population under 200, preserves an authentic rural Riojan character around the spa.
