Hedionda Natural Thermal Baths in Casares


In the natural area of the Sierra de Utrera, we can find natural thermal baths known as Baños de la Hedionda, which are known for the healing properties of their waters.

What are the Hedionda natural thermal baths like?

They are sulfurous ferruginous baths located in a wonderful location.

The spa area has a square shape of approximately 6 meters long, with a spherical vaulted room and two galleries also covered by vaults, all under the water. Subsequent remodeling led to the expansion of the walls and channels that were brought to light in the early 90s. In addition, since 2016, these baths have natural pools.

The materials used in the construction of the Baños de la Hedionda are: lime concrete, stones, and double or triple rows of solid bricks.

Hedionda Natural Thermal Baths

Where are the Hedionda natural thermal baths?

The Baños de la Hedionda are located in the town of Casares in the Sierra de Utrera, declared a Site of Cultural Interest (BIC). They are located on the right bank of the Albarrán stream, very close to the limit with the municipality of Manilva.


The most popular legend tells that in the 1st century BC, during the second civil war between Caesar and Pompey, Julius Caesar’s Roman troops were camped near the spring waiting for the confrontation. The waters of this spring were turquoise in color and emitted an unpleasant odor.

Many of Caesar’s soldiers suffered from severe scabies infections, which prevented them from fighting optimally, but after bathing in these waters, their itching was reduced, thus confirming the healing power of the waters of the Manilva River. In addition, it is also said that Julius himself was cured of a herpetic infection and ordered the construction of the baths that are still preserved today.

Another legend says that the devil exhaled his last breath here when he was expelled by Santiago.

The origin of these sources seems to be in the Roman era. Although during the Muslim era, its structure and channeling system were modified, acquiring the appearance we see today.

Regardless of the legends, the oldest geographic treatises of the municipality of Casares refer to the healing properties of the Hedionda fountain, and people still visit them to benefit from their healing properties.


The water in these baths of the Hedionda maintains a constant temperature of 18-21 degrees, both in winter and summer. Although if you plan to take care of your skin with the clay from its spring and want to dry the mud in the sun, it is recommended to visit it in summer.

The locals offer recommendations to make the most of the healing properties of the waters. First, take a bath inside the thermal bath or in the riverbed itself. Then, apply the greenish clay all over the body, including the hair. Next, let the layer of mud dry in the sun, and finally, once the mud is dry, bathe in the river itself.

Due to the high influx of people who come to bathe in these healing waters, the Casares Town Council has established a series of measures, among which the limitation of the capacity in the premises stands out, to a maximum of 24 people. Therefore, to access during the established peak hours, from 12:00 to 19:00 from July to September, reservations will be mandatory.
