The Mar Menor has 73 km of coastline, and its banks are happening beaches with clear waters and shallow (maximum depth is not greater than 7 meters.) Hardened by the sun and very rich in salt and iodine.
In the south of this small sea rise the islands of La Perdiguera, Mayor, Round, Deer, Subject, and in summer there are daily excursions to one of them.
In its short history, the earliest dating from the Palaeolithic sites found, although the settlements which have more information and have been found more traces are from the Roman and Arabic.
The Romans appreciated very much the area where they developed a large salted fish industry. There was also an important maritime traffic, which indicates that a settlement had to be primarily industrial.
Old chronicles, as the Book of Hunting by Alfonso X, talk about the wealth of wildlife and scenic beauty of this area. Deer Island retains the toponymy of the animal that lived and Pinatar old boars were charged and are still thrushes, sandpipers, ducks and other waterfowl are wintering in the warm waters of this singular Tues.
Similarly, Arabs and Carthaginians in the writings of the time spoke of the importance of salt located in the north, now one of the most important wetlands in Spain, as well as fishing gear called weirs, which still preserved, once restored.
The passage of all these civilizations for our Mar Menor has been for centuries, a spirit of tourism, both its people and its way of life, and already over one hundred years is considered an important international tourist center.
