Arroyo Vaquero has its source in the southern foothills of Sierra Bermeja, in the town of Casares, with its very short path to reach the sea.
Therefore , it has to climb steep gradient in a few kilometers which, together with materials strength by running, force it to fit into existing rock in some sections north of the AP-7 although from viaduct that road, considerably the slope d of the stream ecreases and the bottom of its narrow valley begins to widen and take the form of trough.
The stream has a temporary water regime of watercourses, with a severe drought in the summer which means that, in the lower reaches, the water disappears and in times of heavy winter rains, its volume increases considerably.
The landscape through which the river flows is steep until you reach the section between the AP-7 and A-7, which becomes a ridged relief becoming practically flat in the section between the A-7 and the estuary.
Regard to the uses there is a predominance of forest use in the stretch north of the AP-7, with the exception of some areas affected by extractive uses, while in the south section of this route has developed residential urban uses and sports (golf) and further south until you reach the A-7, areas of tree crops and orchards with areas of grassland and scrub alternate.
As for the environmental values of the area include no relevant species of flora or fauna but stresses the scenic value of the existing section between the A-7 and El Rodeo and Estepona Golf urbanizations, because it still maintains its rural and natural character.
