The Ariño spa is located in the valley of the River Martín, at the foot of the Sierra de Arcos. The facilities take advantage of the mineral-medicinal waters that arise from the nearby Ariño springs. The springs have a flow of up to 700 liters per second of sulphated, calcium and magnesium water, between 22 and 24º.
In addition to the spa itself, the facilities include accommodation and a restaurant.
