The Isla de Terreros and Isla Negra Natural Monument is on the east coast of Almeria, bordering Murcia province and opposite the town of San Juan de Terreros in Pulpí,.

These two islands are of volcanic origin. They are close to the coast and have sparse vegetation. However, their environmental importance comes from the variety of marine bird life with nesting and breeding grounds there. Isla de Terreros is the larger of the two and is further from the coast, and has the largest community of nesting marine birds in Almeria. These include endangered species such as Cory's shearwater, which only goes ashore to breed, and the European storm-petrel. Other interesting species are the yellow-legged gull and the swift. Its marine beds are also very rich. They have large meadows of a plant that is exclusive to the Mediterranean coast: Posidonea oceanica, which provides shelter, food and breeding grounds for many species of fish, crustaceans, cephalopods and marine invertebrates.

Besides the rich flora and fauna, the beaches are also very beautiful. All along the coast there are volcanic outcrops that contrast with the sand and the blues of the sea. Along the coast you can see the old saltmeadow cordgrass stone ovens. This profession has now fallen into disuse, with the old fisherman cottages, known as "terreros" dug out of the walls of the cliffs remaining. Other places to visit are La Herradura castle and San Juan de los Terreros castle.
