Termas de Arnedillo is a long-established thermal spa resort set in the dramatic Cidacos River gorge in La Rioja, where sodium-rich and bicarbonate-rich spring waters emerging at around forty-eight degrees Celsius have drawn visitors seeking relaxation and well-being in a long thermal tradition since the early nineteenth century. The gorge setting is spectacular — ochre limestone cliffs rise sharply above the spa buildings, and a ruined hilltop castle reachable by a forty-five-minute footpath rewards visitors with vertiginous views across the canyon and the Riojan countryside spreading beyond in every direction. La Rioja's world-renowned wine country, including the historic bodegas of Haro just thirty kilometres away where some of Spain's finest Tempranillo is aged, makes Arnedillo an ideal pairing of thermal escape and wine discovery through one of Spain's most scenically compelling inland regions.

Insider tip — Climb up to the castle ruins for a dizzying view over the Cidacos Gorges — 45 min walk from the balneario. After treatments, explore the Rioja wineries of Haro (30 km): some offer tours in French. The Sierra de Cameros Nature Park in the hinterland offers hikes through surprisingly desert-like landscapes.
