It is the favorite destination of many tourists for several reasons: the sun always shines in the Mar Menor, the high concentration of minerals in the water and the low waves. You can walk the perimeter of the Mar Menor almost in its entirety. There is a strait of about 200 meters that separates La Manga and the breakwater of San Pedro del Pinatar.
