• The presence of the Breña y Marismas del Barbate Natural Park helps maintain the natural characteristics of much of the coastal strip. This natural area has one of the most remarkable landscapes on the Atlantic coast of Cadiz, with dramatic cliffs of over 100 m high, as the ones at Torre del Tajo, and at Caños de Meca, somewhat lower in height. In some respects these cliffs arise springs drinking water discharging into small creeks, giving it a rich landscape. It has been declared as a Special Protection Area (SPA) and Place of Community Interest (SCI).

• Another protected area within the region is the Tombolo de Trafalgar Natural Monument, sandstone small island located between the inlets of Conil and Barbate and joined the coast by a double cross line of sand that give rise to an arrow. At its southern part, around the lighthouse, there are various archaeological sites. Compared to its shores took place in 1805 the famous battle of Trafalgar. It was declared a Site of Community Interest (SCI).

Others sites declared as Site of Community Interest are: the Pinar de Roche, in the Municipal Term of Conil de la Frontera and with an extension of approximate 6,9 km²; Acebuchales de la Campiña Sur de Cádiz (wild olive forest in the Cadiz countryside), with an approximate extension of 264,4 km², located in the central part of the county, includes the municipalities of Barbate, Conil and Vejer de la Frontera and the Salado River together with its main tributaries in its passage through the border of Vejer and Conil.
