The Mar Menor, meaning little sea, is a unique sea lagoon and well worth a visit. It is separated from the Mediterranean by a narrow piece of land called the La Manga Strip. The strip starts just after Cabo de Palos at the south end of the Mar Menor and continues for 21 kilometres towards San Pedro del Pinatar at the north end. Before it reaches San Pedro there is a small channel which allows water in and out of the Mar Menor. The waters enclosed by the strip are always calm, never colder than 18oC and are very rich in salts and iodine making it unique.
