The Guadalevín is a tributary of the river Guadiaro in Málaga, Andalusia, Spain. Its gorge divides the city of Ronda where it is spanned by three bridges, Puente Nuevo, Puente Viejo and Puente Romano.

The following is a translation of the Spanish Wikipedia article on the Guadalevin.

The Guadalevín River is a short river in the south of Spain (Andalusia) that runs entirely through the Serranía de Ronda, west of the province of Málaga, Spain. It originates in the Sierra de las Nieves, in the municipality of Igualeja, and ends at the Guadiaro river; it is thus in the Mediterranean basins of Andalusia and belongs to its hydrological demarcation. Almost all of its course has been declared a Special Area of Conservation (or ZEC to use the Spanish acronym).

Its name comes from the Arabic “Wadi-al-Laban” (river of milk).

The headwaters of the Guadalevín river is located in the Sierra de las Nieves Natural Park, specifically in the Cañada del Cuerno, the nucleus of the Pinsapar de Ronda. Downstream, the Fuenfría arroyo joins it and it receives contributions from the Oreganal mountain range, including the Malillo spring. From there it is also called the Rio Grande.

Subsequently, it passes through the city of Ronda where it sculpts the Tajo Gorge and enters the Ronda plateau under the name of Guadalevín. In the area of La Indiana it meets the Guadalcobacín river, formed among others by the Ventilla arroyo, a turbulent course that flows through a river gorge with remarkable geodiversity in the municipality of Arriate.

The juncture of the Guadalevín and Guadalcobacín marks the point where the start of the Guadiaro river is generally considered to be located, although some authors assert that it happens a few kilometers below, when the [Guadares] river joins it from the Cueva del Gato.

The Guadalevín River zone is made up of gypsum marl, sandstone and limestone.
