Mar Menor (Spanish pronunciation: [ˌmaɾ meˈnoɾ], "Minor sea" or "Smaller Sea"; the Mediterranean Sea is also called Mar Mayor ["Larger Sea"] in the region) is a coastal saltwater lagoon in the Iberian Peninsula located south-east of the Autonomous Community of Murcia, Spain, near Cartagena. Four municipalities lie by the Mar Menor, Cartagena, Los Alcázares, San Javier and San Pedro del Pinatar. With a surface area of 135 km2, a coastal length of 70 km, and warm and clear water no more than 7 metres in depth, it is the largest lagoon in Spain. 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. Its relatively high salinity, which aids flotation, and remarkable sporting infrastructures makes it a popular place for a wide variety of water sports.
