The lagoon is separated from the Mediterranean Sea by La Manga ("the sleeve", in Spanish), a sandbar 22 km in length whose width ranges from 100 to 1,200 metres, with Cape Palos in its south-eastern vertex making for the lagoon's roughly triangular shape. There are five islets located within the lagoon, namely Perdiguera islet, Mayor islet, Ciervo islet, Redonda islet and del Sujeto islet.
