The water in the Mijares River at this point originates from an underground reservoir system that circulates through karst limestone aquifers.
The constant 25-degree temperature is due to the deep circulation of groundwater reaching depths where it is heated by the Earth's geothermal gradient.
The water flow volume is regulated by the nearby Arenoso Reservoir dam operations.
The site features distinct travertine deposits formed by the precipitation of calcium carbonate from the mineral-heavy spring water.
The limestone walls surrounding the area are popular for sport climbing, featuring numerous bolted routes.
El Chorro is a notable geothermal water feature located along the Mijares River in the Montanejos region. It serves as a major outlet for the Fuente de los Baños, where water maintains a constant temperature of approximately 25 degrees Celsius year-round. The area is characterized by steep limestone canyon walls and integrated swimming basins. It functions as a public natural pool site, attracting visitors for its mineral-rich waters and geological setting. The site is part of a larger river recreation zone known for its distinct turquoise water color. Visitors access the riverbed via established paths connecting to the main road, CV-20. The geological formation is influenced by the surrounding mountainous terrain of the Sierra de Espadán natural park.

Bring water shoes to navigate the riverbed comfortably, as the bottom is rocky and uneven.
Visit on weekdays to avoid significant crowds that gather during weekends and Spanish national holidays.
Apply high-protection sunscreen, as there is limited natural shade directly along the river edge.
Do not attempt to dive or jump from the higher canyon walls due to hidden submerged rocks and varying water depth.
The area is accessible year-round, though visitor restrictions or capacity controls may be implemented by the local council during high-summer peak weekends.
Wear non-slip water shoes; avoid using soaps or shampoos in the river to protect the ecosystem; pack out all personal trash.
