At the foot of Jabalcón Hill and on the shores of the Negratín Reservoir, this open-air thermal pool has been attracting bathers since Roman times. Over the centuries, it passed through many hands (including those of the Hieronymite monks of Baza), and in the 18th century it even rivaled the finest spas in Europe, frequented by the Spanish nobility.
The construction of the reservoir in 1985 submerged the old facilities, but the spring never stopped flowing: today it continues to emerge from the fissures of Cerro Jabalcón at a temperature between 35 and 40 °C, forming a natural pool measuring about 30 by 12 meters that overlooks the turquoise waters of the reservoir.
It’s an open-air swimming area, with no enclosure or facilities: just earth, water, and heat, with limestone hillsides and pine forests as a backdrop.
